PROSPECTUS
                                                                   88,714,577




                                                                Common Stock

            This prospectus relates to the offer and sale from time to time of up to 88,714,577 shares of our common stock, par value $0.01 per
share, including an aggregate of 60,800,125 shares of common stock issuable upon exercise of warrants, which are held by the selling
stockholders identified in this prospectus. The shares of common stock and warrants were issued in three separate private placement
transactions each of which private placements was made in reliance on Section 4(2) of the Securities Act of 1933, as amended, which we refer
to as the Securities Act, and Rule 506 promulgated thereunder. For additional information regarding each of the private placements, please see
“Description of Private Placements” beginning on page 22 of this prospectus.

            Pursuant to a registration rights agreement entered into in connection with our recent private placement which closed on March 30,
2012 and April 4, 2012, we agreed to register for resale the shares of common stock issued to the selling stockholders. Investors who
participated in private placements that closed in August 2010 and October 2009 have also exercised their rights, pursuant to registration rights
agreements entered into in connection with those private placements, to include their registrable securities within this registration
statement. We are not selling any common stock under this prospectus and will not receive any of the proceeds from the sale of shares by the
selling stockholders, however we will receive the proceeds of any cash exercise of the warrants.

            The selling stockholders may sell the shares from time to time at the market price quoted on the OTC Bulletin Board at the time of
offer and sale, or at prices related to such prevailing market prices, in negotiated transactions or in a combination of such methods of sale
directly or through brokers. See “Plan of Distribution” beginning on page 96 for additional information on how the selling stockholders may
conduct sales of their shares of common stock.

          Other than underwriting discounts and commissions, and transfer taxes, if any, we have agreed to bear all expenses incurred in
connection with the registration and sale of the common stock offered by the selling stockholders.

         Our common stock is quoted on the OTC Bulletin Board under the symbol “AOLS.” On May 10, 2012, the closing price of our
common stock was $0.31 per share.

          Investing in our common stock involves a high degree of risk. See “Risk Factors” beginning on page 3 for certain risks you
should consider before purchasing any shares.

                                                                RISK FACTORS

You should carefully consider the following information about risks described below, together with the other information contained in this
prospectus and in our other filings with the SEC, before you decide to buy or maintain an investment in our common stock. We believe the risks
described below are the risks that are material to us as of the date of this prospectus. If any of the following risks actually occur, our business,
financial condition, results of operations and future growth prospects would likely be materially and adversely affected. In these
circumstances, the market price of our common stock could decline, and you may lose all or part of your investment.

Risks Related to Our Business

We have operated at a loss and will likely continue to operate at a loss for the foreseeable future.

          We have incurred significant losses over the past five years, including net income of approximately $299,000 for the year ended
September 30, 2011 and net losses of approximately $25,869,000 and $2,296,000 for the years ended September 30, 2010 and 2009,
respectively, and we had an accumulated deficit of approximately $182,412,000 as of September 30, 2011. Our operating losses have been due
primarily to our expenditures for research and development on our drug candidates and for general and administrative expenses and our lack of
significant revenues. Additionally, during 2011 and 2010 we incurred a gain of $3,887,000 and a charge of $21,347,000, respectively, to our
warrant liability related to outstanding warrants, which are non-cash items and do not impact our financial operations or cash needs. We are
likely to continue to incur operating losses until such time, if ever, that we generate significant recurring revenues. We anticipate it will take a
minimum of two years (and possibly longer) for us to generate recurring revenues, since we expect that it will take at least that long before the
development of any of our licensed or other current potential products is completed, marketing approvals are obtained from the FDA and
commercial sales of any of these products can begin, or that we might receive a procurement from the US Government under an Emergency
Use Authorization or Animal Rule Approval.

We need substantial additional funding to continue our operations and may be unable to raise capital when needed, or at all, which would
force us to delay, curtail or eliminate our clinical programs and our product development programs.

         We need to raise substantial additional capital to fund our operations and clinical trials and continue our research and development. In
addition, we may need to raise substantial additional capital to enforce our proprietary rights, defend, in litigation or otherwise, any claims that
we infringe third party patents or other intellectual property rights; and commercialize any of our products that may be approved by the FDA or
any international regulatory authority.

          We received approximately $337,000 in November 2010 from the Internal Revenue Service ("IRS") for the Aualifying Therapeutic
Discovery Grant Program ("QTDP"). On December 28, 2010, we raised gross proceeds of $1,000,000 through the sale of our common stock
and warrants to two institutional investors as a result of these investors exercising an option for additional investment that they received in our
August 2010 financing. On March 30, 2012 and April 4, 2012, we closed a private placement through which we raised gross proceeds of
approximately $660,000 through the sale of our common stock and warrants to a group of accredited investors. As of March 31, 2012, we had
cash of approximately $390,000. We expect to use these funds, including any additional funds received pursuant to the issuance of additional
securities and the exercise of outstanding warrants to purchase our capital stock, to continue the development of our drug candidates, to expand
the development of our drug pipeline and for working capital.

          In order to fund on-going operating cash requirements, or to accelerate or expand our oncology and other programs we may need to
raise significant additional funds. We are continuously considering strategic and financial options available to us, including public or private
equity offerings, debt financings or collaboration arrangements. If we raise additional funds by issuing securities, our stockholders will
experience dilution of their ownership interest. Debt financings, if available, may involve restrictive covenants and require significant interest
payments. If we do not receive additional financing to fund our operations not reimbursed under the BARDA Contract, or if BARDA does not
exercise any additional options under the BARDA Contract and we are unable to raise sufficient capital for operations, we would have to
discontinue some or all of our activities, merge with or sell, lease or license some or all of our assets to another company, or cease operations
entirely, and our stockholders might lose all or part of their investments.

         In addition, if our catalytic antioxidant program shows scientific progress, we will need significant additional funds to move therapies
through the preclinical stages of development and clinical trials. If we are unable to raise the amount of capital necessary to complete
development and reach commercialization of any of our catalytic antioxidant products, we will need to delay or cease development of one or
more of these products or partner with another company for the development and commercialization of these products.


                                                                         3
Our independent registered public accounting firm has expressed substantial doubt about our ability to continue as a going concern .

          In its audit opinion issued in connection with our consolidated balance sheets as of September 30, 2011 and our consolidated
statements of operations, stockholder’s equity and cash flows for the years ended September 30, 2011, our independent registered public
accounting firm has expressed substantial doubt about our ability to continue as a going concern given our recurring net losses, negative cash
flows from operations and working capital deficiency. In addition, in its audit opinion issued in connection with our consolidated balance
sheets as of September 30, 2010 and our consolidated statements of operations, stockholder’s equity and cash flows for the years ended
September 30, 2010 and 2009, our prior independent registered public accounting firm expressed substantial doubt about our ability to continue
as a going concern given our recurring net losses, negative cash flows from operations and working capital deficiency. The accompanying
financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities
and commitments in the normal course of business. The financial statements do not include any adjustments relating to the recoverability and
classification of recorded asset amounts or amounts of liabilities that might be necessary should we be unable to continue in existence.

We have a history of operating losses and expect to continue to incur substantial losses and may never become profitable.

         We have no products approved for commercialization in the United States or abroad. Our drug candidates are still being developed,
and all but our AEOL 10150 candidate are still in early stages of development. Our drug candidates will require significant additional
development, clinical trials, regulatory clearances or approvals by the FDA and additional investment before they can be commercialized in the
United States.

         Our likelihood for achieving profitability will depend on numerous factors, including success in:

             ● developing our existing drug candidates and developing and testing new drug candidates;

             ● carrying out our intellectual property strategy;

             ● establishing our competitive position;

             ● achieving third-party collaborations;

             ● receiving regulatory approvals;

             ● manufacturing and marketing products; and

             ● receiving government funding and identifying new government funding opportunities.

         Many of these factors will depend on circumstances beyond our control. We may not achieve sufficient revenues for profitability.
Even if we do achieve profitability, we may not be able to can sustain or increase profitability on a quarterly or annual basis in the future. If
revenues grow more slowly than we anticipate, or if operating expenses exceed our expectations or cannot be adjusted accordingly, then our
business, results of operations, financial condition and cash flows will be materially and adversely affected.

           The current turmoil impacting the financial markets and the possibility that financial institutions may consolidate or cease operations
has resulted in a tightening in the credit markets, a low level of liquidity in many financial markets and extreme volatility in fixed income,
credit, currency and equity markets. As a result, we may not be successful in obtaining sufficient financing on commercially reasonable terms,
or at all. Our requirements for additional capital may be substantial and will be dependent on many factors, including the success of our
research and development efforts, our ability to commercialize and market products, our ability to successfully pursue our licensing and
collaboration strategy, the receipt of government funding, competing technological developments, costs associated with the protection of our
intellectual property and any future change in our business strategy.


                                                                         4
         As of March 31, 2012, we had an accumulated deficit of $176,672,000 from our research, development and other activities. We have
not generated material revenues from product sales and do not expect to generate product revenues sufficient to support us for at least several
more years.

Our research and development (“R&D”) activities are at an early stage and therefore might never result in viable products.

         Our catalytic antioxidant program is in the early stages of development, involves unproven technology, requires significant further
R&D and regulatory approvals and is subject to the risks of failure inherent in the development of products or therapeutic procedures based on
innovative technologies. These risks include the possibilities that:

             ● any or all of these proposed products or procedures are found to be unsafe or ineffective or otherwise fail to receive
                  necessary regulatory approvals;

             ● the proposed products or procedures are not economical to market or do not achieve broad market acceptance;

             ● third parties hold proprietary rights that preclude us from marketing the proposed products or procedures; and

             ● third parties market a superior or equivalent product.

         Further, the timeframe for commercialization of any product is long and uncertain because of the extended testing and regulatory
review process required before marketing approval can be obtained. We may not be able to successfully develop or market any of our proposed
products or procedures. If we are not able to successfully market any product, our business will suffer.

If our products are not successfully developed and eventually approved by the FDA, we may be forced to reduce or terminate our
operations.

          All of our drug candidates are at various stages of development and must be approved by the FDA or similar foreign governmental
agencies before they can be marketed. The process for obtaining FDA and foreign regulatory approval is both time-consuming and costly, with
no certainty of a successful outcome. This process typically requires extensive preclinical and clinical testing, which may take longer or cost
more than we anticipate, and may prove unsuccessful due to numerous factors. Drug candidates that may appear to be promising at early stages
of development may not successfully reach the market for a number of reasons. The results of preclinical and initial clinical testing of these
drug candidates may not necessarily indicate the results that will be obtained from later or more extensive testing. A number of companies in
the pharmaceutical and biotechnology industries have suffered significant setbacks in advanced clinical trials, even after obtaining promising
results in earlier trials.

         Numerous factors could affect the timing, cost or outcome of our drug development efforts, including the following:

             ● Difficulty in securing research laboratories to conduct research activities;

             ● Difficulty in securing centers to conduct trials;

             ● Difficulty in enrolling patients in conformity with required protocols or projected timelines;

             ● Unexpected adverse reactions by patients in trials;

             ● Difficulty in obtaining clinical supplies of the product;

             ● Changes in the FDA’s or other regulatory body’s requirements for our testing during the course of that testing;

             ● Inability to generate statistically significant data confirming the efficacy of the product being tested;

             ● Modification of the drug during testing; and


                                                                           5
             ● Reallocation of our limited financial and other resources to other clinical programs.

          It is possible that none of the products we develop will obtain the regulatory approvals necessary for us to begin commercializing
them. The time required to obtain FDA and other approvals is unpredictable but often can take years following the commencement of clinical
trials, depending upon the nature of the drug candidate. Any analysis we perform on data from clinical activities is subject to confirmation and
interpretation by regulatory authorities, which could delay, limit or prevent regulatory approval. Any delay or failure in obtaining required
approvals could have a material adverse effect on our ability to generate revenues from the particular drug candidate and we may not have the
financial resources to continue to develop our drug candidates and, as a result, may have to terminate our operations.

If we do not reach the market with our products before our competitors offer products for the same or similar uses, or if we are not effective
in marketing our products, our revenues from product sales, if any, will be reduced.

         We face intense competition in our development activities. Many of our competitors are fully integrated pharmaceutical companies
and more established biotechnology companies, which have substantially greater financial, technical, sales and marketing and human resources
than we do. These companies might succeed in obtaining regulatory approval for competitive products more rapidly than we can for our
products. In addition, competitors might develop technologies and products that are less expensive and perceived to be safer or more effective
than those being developed by us, which could impair our product development and render our technology obsolete.

We are and expect to remain dependent upon collaborations with third parties for the development of new products, and adverse events
involving these collaborations could prevent us from developing and commercializing our drug candidates and achieving profitability.

         We currently license from third parties, and do not own, rights under patents and certain related intellectual property for the
development of our drug candidates. In addition, we expect to enter into agreements with third parties to license rights to our drug candidates.
We might not be able to enter into or maintain these agreements on terms favorable to us, if at all. Further, if any of our current licenses were to
expire or terminate, our business, prospects, financial condition and results of operations could be materially and adversely affected.

Our research and development activities rely on technology licensed from third parties, and termination of any of those licenses would
result in loss of significant rights to develop and market our products, which would impair our business, prospects, financial condition and
results of operations.

         We have exclusive worldwide rights to our antioxidant small molecule technology through license agreements with Duke University
and the National Jewish Health. Each license generally may be terminated by the licensor if we fail to perform our obligations under the
agreement, including obligations to develop the compounds and technologies under license. If terminated, we would lose the right to develop
the products, which could adversely affect our business, prospects, financial condition and results of operations. The license agreements also
generally require us to meet specified milestones or show reasonable diligence in development of the technology. If disputes arise over the
definition of these requirements or whether we have satisfied the requirements in a timely manner, or if any other obligations in the license
agreements are disputed by the other party, the other party could terminate the agreement, and we could lose our rights to develop the licensed
technology.

         If new technology is developed from these licenses, we may be required to negotiate certain key financial and other terms, such as
royalty payments, for the licensing of this future technology with these research institutions, and it might not be possible to obtain any such
license on terms that are satisfactory to us, or at all.

We now rely, and will continue to rely, heavily on third parties for product and clinical development, manufacturing, marketing and
distribution of our products.

         We currently depend heavily and will depend heavily in the future on third parties for support in product development, clinical
development, manufacturing, marketing and distribution of our products. The termination of some or all of our existing collaborative
arrangements, or our inability to establish and maintain collaborative arrangements, could have a material adverse effect on our ability to
continue or complete clinical development of our products.


                                                                         6
           We rely on contract clinical research organizations (“CROs”) for various aspects of our clinical development activities including
clinical trial monitoring, data collection and data management. As a result, we have had and continue to have less control over the conduct of
clinical trials, the timing and completion of the trials, the required reporting of adverse events and the management of data developed through
the trial than would be the case if we were relying entirely upon our own staff. Although we rely on CROs to conduct our clinical trials, we are
responsible for confirming that each of our clinical trials is conducted in accordance with the investigational plan and protocol. Moreover, the
FDA and foreign regulatory agencies require us to comply with GCPs for conducting, recording and reporting the results of clinical trials to
assure that the data and results are credible and accurate and that the trial participants are adequately protected. Our reliance on third parties
does not relieve us of these responsibilities and requirements.

          The third parties on which we rely may have staffing difficulties, may undergo changes in priorities or may become financially
distressed, adversely affecting their willingness or ability to conduct our trials. We may experience unexpected cost increases that are beyond
our control. Any failure of such CROs to successfully accomplish clinical trial monitoring, data collection and data management and the other
services they provide for us in a timely manner and in compliance with regulatory requirements could have a material adverse effect on our
ability to complete clinical development of our products and obtain regulatory approval. Problems with the timeliness or quality of the work of
a CRO may lead us to seek to terminate the relationship and use an alternate service provider. However, making such changes may be costly
and would likely delay our trials, and contractual restrictions may make such a change difficult or impossible. Additionally, it may be difficult
to find a replacement organization that can conduct our trials in an acceptable manner and at an acceptable cost.

If BARDA opts not to exercise its options under the BARDA Contract, we would be dependent upon grants from NIH for continued
development of AEOL 10150 for Lung-ARS, or we would need to curtail our development program in this area significantly and we may be
placed at a competitive disadvantage in addressing this market opportunity.

         During the fiscal year ended September 30, 2011, we received 100% of our revenues from our agreement with the Biomedical
Advanced Research and Development Authority, which we refer to as BARDA, for the development of AEOL 10150 as a MCM against
Lung-ARS, we refer to this agreement as the BARDA Contract. These revenues have funded some of our personnel and other R&D costs and
expenses. Pursuant to the BARDA Contract, we will receive approximately $10.4 million in the base period of performance and up to an
additional approximately $108 million in options over four years, if the options are exercised by BARDA, for a total contract value of up to
approximately $118.4 million. Under the terms of the BARDA Contract, BARDA may elect not to exercise some or all of the additional
options. Because a significant portion of our current revenues are generated from the BARDA Contract, if BARDA does not exercise its
options under the BARDA Contract, our ability to develop AEOL 10150 as an MCM for Lung-ARS could be negatively impacted, which could
harm our competitive position and materially and adversely affect our business, financial condition and results of operations. On April 9, 2012,
we announced that BARDA had issued a Notice of Intent to Exercise two options valued at $9.1 million. On April 16, 2012, BARDA exercised
the two options. The bulk of the options are for the period of performance beginning April 1, 2012 and ending March 31, 2013, and include
funding for murine and non-human primate efficacy studies in Lung Acute Radiation Syndrome (Lung-ARS), good manufacturing practice
manufacturing, and project management costs.

Necessary reliance on the “Animal Rule” in conducting trials is time-consuming and expensive.

          To obtain FDA approval for our drug candidate for a bioterrorism indication under current FDA regulations, we are required to utilize
animal model studies for efficacy and provide animal and human safety data under the “Animal Rule.” For many of the biological and chemical
threats, animal models are not yet available, and as such we are developing, or will have to develop, appropriate animal models, which is a
time-consuming and expensive research effort. Further, we may not be able to sufficiently demonstrate the animal correlation to the satisfaction
of the FDA, as these corollaries are difficult to establish and are often unclear. The FDA may decide that our data are insufficient for approval
and require additional preclinical, clinical or other studies, refuse to approve our products, or place restrictions on our ability to commercialize
those products. Further, other countries do not, at this time, have established criteria for review and approval of these types of products outside
their normal review process; i.e., there is no “Animal Rule” equivalent, and consequently we may not be able to make a submission for
marketing approval in foreign countries based on such animal data.

          Additionally, few facilities in the U.S. and internationally have the capability to test animals with radiation, nerve agents, or other
lethal biotoxins or chemical agents or otherwise assist us in qualifying the requisite animal models. We have to compete with other biodefense
companies for access to this limited pool of highly specialized resources. We therefore may not be able to secure contracts to conduct the
testing in a predictable timeframe, cost-effectively or at all.


                                                                         7
Even if we succeed in commercializing our drug candidates, we may not become profitable and manufacturing problems or side effects
discovered at later stages can further increase costs of commercialization.

           Any drugs resulting from our research and development efforts may not become commercially available. Even if we succeed in
developing and commercializing our drug candidates, we may never generate sufficient or sustainable revenues to enable us to be profitable.
Even if effective, a product that reaches the market may be subject to additional clinical trials, changes to or re-approvals of our manufacturing
facilities or a change in labeling if we or others identify side effects or manufacturing problems after a product is on the market. This could
harm sales of the affected products and could increase the cost and expenses of commercializing and marketing them. It could also lead to the
suspension or revocation of regulatory approval for the products.

         We and our contract manufacturing organizations ("CMOs") will also be required to comply with the applicable FDA current good
manufacturing practice (“cGMP”) regulations. These regulations include requirements relating to quality control and quality assurance as well
as the corresponding maintenance of records and documentation. Manufacturing facilities are subject to inspection by the FDA. These facilities
must be approved to supply licensed products to the commercial marketplace. We and our contract manufacturers may not be able to comply
with the applicable cGMP requirements and other FDA regulatory requirements. Should we or our contract manufacturers fail to comply, we
could be subject to fines or other sanctions or could be prohibited from marketing any products we develop.

Political or social factors may delay or impair our ability to market our products and our business may be materially adversely affected.

         Products developed to treat diseases caused by, or to combat the threat of, bioterrorism will be subject to changing political and social
environments. The political and social responses to bioterrorism have been unpredictable. Political or social pressures may delay or cause
resistance to bringing our products to market or limit pricing of our products, which would harm our business. Changes to favorable laws, such
as Project BioShield, could have a material adverse effect on our business, prospects, financial condition and results of operations.

Legislation limiting or restricting liability for medical products used to fight bioterrorism is new, and we cannot be certain that any such
protection will apply to our products or if applied what the scope of any such coverage will be.

         The U.S. Public Readiness Act was signed into law in December 2005 (the “Public Readiness Act”) and creates general immunity for
manufacturers of countermeasures, including security countermeasures (as defined in Section 319F-2(c)(1)(B) of the Public Readiness Act),
when the U.S. Secretary of Health and Human Services issues a declaration for their manufacture, administration or use. The declaration is
meant to provide general immunity from all claims under state or federal law for loss arising out of the administration or use of a covered
countermeasure. Manufacturers are excluded from this protection in cases of willful misconduct. The Secretary of Health and Human Services
may not make declarations that would cover any of our other drug candidates or the U.S. Congress may not act in the future to reduce coverage
under the Public Readiness Act or it may repeal it altogether.

          Upon a declaration by the Secretary of Health and Human Services, a compensation fund would be created to provide “timely,
uniform and adequate compensation to eligible individuals for covered injuries directly caused by the administration or use of a covered
countermeasure.” The “covered injuries” to which the program applies are defined as serious physical injuries or death. Individuals are
permitted to bring a willful misconduct action against a manufacturer only after they have exhausted their remedies under the compensation
program. A willful misconduct action could be brought against us if an individual(s) has exhausted his or her remedies under the compensation
program, which could thereby expose us to liability. Furthermore, the Secretary of Health and Human Services may not issue a declaration
under the Public Readiness Act to establish a compensation fund. We may also become subject to standard product liability suits and other
third party claims if products we develop which fall outside of the Public Readiness Act cause injury or if treated individuals subsequently
become infected or otherwise suffer adverse effects from such products.

Healthcare reform measures and other statutory or regulatory changes could adversely affect our business.

          The pharmaceutical and biotechnology industries are subject to extensive regulation, and from time to time legislative bodies and
governmental agencies consider changes to such regulations that could have significant impact on industry participants. For example, in light of
certain highly-publicized safety issues regarding certain drugs that had received marketing approval, the U.S. Congress is considering various
proposals regarding drug safety, including some which would require additional safety studies and monitoring and could make drug
development more costly. We are unable to predict what additional legislation or regulation, if any, relating to safety or other aspects of drug
development may be enacted in the future or what effect such legislation or regulation would have on our business.


                                                                        8
          The business and financial condition of pharmaceutical and biotechnology companies are also affected by the efforts of governments,
third-party payors and others to contain or reduce the costs of healthcare to consumers. In the United States and various foreign jurisdictions
there have been, and we expect that there will continue to be, a number of legislative and regulatory proposals aimed at changing the healthcare
system, such as proposals relating to the reimportation of drugs into the U.S. from other countries (where they are then sold at a lower price)
and government control of prescription drug pricing. The pendency or approval of such proposals could result in a decrease in our share price
or limit our ability to raise capital or to obtain strategic collaborations or licenses.

The current disruptions in the financial markets could affect our ability to obtain additional debt financing on favorable terms (or at all)
and have other adverse effects on us.

          The United States credit markets have experienced historic dislocations and liquidity disruptions which have caused financing to be
unavailable in many cases and even if available caused spreads on prospective debt financings to widen considerably. These circumstances
have materially impacted liquidity in the debt markets, making financing terms for borrowers able to find financing less attractive, and in many
cases have resulted in the unavailability of certain types of debt financing. Continued uncertainty in the credit markets may negatively impact
our ability to access debt financing on favorable terms or at all. In addition, Federal legislation to deal with the disruptions in the financial
markets could have an adverse affect on our financial condition and results of operations.

We will need to enter into collaborative arrangements for the manufacturing and marketing of our drug candidates, or we will have to
develop the expertise, obtain the additional capital and invest the resources to perform those functions internally.

         We do not have the staff or facilities to manufacture or market any of the drug candidates being developed in our catalytic antioxidant
program. As a result, we will need to enter into collaborative arrangements to commercialize, manufacture and market products that we expect
to emerge from our catalytic antioxidant program, or develop the expertise within our company. We might not be successful in entering into
such third party arrangements on terms acceptable to us, if at all. If we are unable to obtain or retain third-party manufacturing or marketing on
acceptable terms, we may be delayed in our ability to commercialize products, which could have a material adverse effect on our business,
prospects, financial condition and results of operations. Substantial additional funds and personnel would be required if we needed to establish
our own manufacturing or marketing operations. We may not be able to obtain adequate funding or establish these capabilities in a
cost-effective or timely manner, which could have a material adverse effect on our business, prospects, financial condition and results of
operations.

A failure to obtain or maintain patent and other intellectual property rights would allow others to develop and sell products similar to ours,
which could impair our business, prospects, financial condition and results of operations.

          The success of our business depends, in part, on our ability to establish and maintain adequate protection for our intellectual property,
whether owned by us or licensed from third parties. We rely primarily on patents in the United States and in other key markets to protect our
intellectual property. If we do not have adequate patent protection, other companies could develop and sell products that compete directly with
ours, without incurring any liability to us. Patent prosecution, maintenance and enforcement on a global basis are time-consuming and
expensive, and many of these costs must be incurred before we know whether a product covered by the claims can be successfully developed or
marketed.

          Even if we expend considerable time and money on patent prosecution, a patent application may never issue as a patent. We can never
be certain that we were the first to invent the particular technology or that we were the first to file a patent application for the technology
because patent applications in the United States and elsewhere are not typically published for public inspection for at least 18 months from the
date when they are filed. It is always possible that a competitor is pursuing a patent for the same invention in the United States as we are and
has an earlier invention date. In some jurisdictions outside of the United States, priority of invention is determined by the earliest effective
filing date, not the date of invention. Consequently, if a third party pursues the same invention and has an earlier filing date, patent protection
outside the United States would be unavailable to us. Also, outside the United States, an earlier date of invention cannot overcome a date of
publication that precedes the earliest effective filing date. Accordingly, the patenting of our proposed products would be precluded outside the
United States if a prior publication anticipates the claims of a pending application, even if the date of publication is within a year of the filing of
the pending application.


                                                                          9
         Even if patents issue, the patent claims allowed might not be sufficiently broad to offer adequate protection for our technology against
competitive products. Patent protection differs from country to country, giving rise to increased competition from other products in countries
where patent coverage is either unavailable, weak or not adequately enforced, if enforced at all. Once a patent issues, we still face the risk that
others will try to design around our patent or will try to challenge the validity of the patent. The cost of defending against a challenge to one or
more of our patents could be substantial and even if we prevailed, there could be no assurance that we would recover damages.

If a third party were to bring an infringement claim against us, we would incur significant costs in our defense; if the claim were
successful, we would need to develop non-infringing technology or obtain a license from the successful patent holder, if available.

          Our business also depends on our ability to develop and market products without infringing on the proprietary rights of others or being
in breach of our license agreements. The pharmaceutical industry is characterized by a large number of patents, patent filings and frequent and
protracted litigation regarding patent and other intellectual property rights. Many companies have numerous patents that protect their
intellectual property rights. Third parties might assert infringement claims against us with respect to our drug candidates and future products. If
litigation were required to determine the validity of a third party’s claims, we could be required to spend significant time and financial
resources, which could distract our management and prevent us from furthering our core business activities, regardless of the outcome. If we
did not prevail in the litigation, we could be required to pay damages, license a third party’s technology, which may not be possible on terms
acceptable to us, or at all, or discontinue our own activities and develop non-infringing technology, any of which could prevent or significantly
delay pursuit of our development activities.

Protection of trade secret and confidential information is difficult, and loss of confidentiality could eliminate our competitive advantage.

        In addition to patent protection, we rely on trade secrets, proprietary know-how and confidential information to protect our
technology. We use confidentiality agreements with our employees, consultants and collaborators to maintain the proprietary nature of this
technology. However, confidentiality agreements can be breached by the other party, which would make our trade secrets and proprietary
know-how legally available for use by others. There is generally no adequate remedy for breach of confidentiality obligations. In addition, the
competitive advantage afforded by trade secrets is limited because a third party can independently discover or develop something identical to
our own trade secrets or know-how, without incurring any liability to us.

          In addition, if our current or former employees, consultants or collaborators were to use information improperly obtained from others
(even if unintentional), we may be subject to claims as to ownership and rights in any resulting know-how or inventions.

If we cannot retain or hire qualified personnel or maintain our collaborations, our programs could be delayed and may be discontinued.

         As of March 31, 2012, we had six full-time employees. We utilize consultants to assist with our operations and are highly dependent
on the services of our executive officers. We do not maintain “key person” life insurance on any of our personnel. We also are dependent on
our collaborators for our research and development activities. The loss of key executive officers or collaborators could delay progress in our
research and development activities or result in their termination entirely.

         We believe that our future success will depend in large part upon our ability to attract and retain highly skilled scientific and
managerial personnel. We face intense competition for these kinds of personnel from other companies, research and academic institutions,
government entities and other organizations. If we fail to identify, attract and retain personnel, we may be unable to continue the development
of our drug candidates, which would have a material adverse effect on our business, prospects, financial condition and results of operations.


                                                                         10
We face the risk of product liability claims which could exceed our insurance coverage and deplete our cash resources.

         The pharmaceutical and biotechnology industries expose us to the risk of product liability claims alleging that use of our drug
candidates caused an injury or harm. These claims can arise at any point in the development, testing, manufacture, marketing or sale of
pharmaceutical products and may be made directly by patients involved in clinical trials of our products, by consumers or healthcare providers
or by organizations selling our products. Product liability claims can be expensive to defend, even if the product did not actually cause the
alleged injury or harm.

         Insurance covering product liability claims becomes increasingly expensive as a product candidate moves through the development
pipeline to commercialization. We have limited product liability insurance coverage for our clinical trials and this coverage may not be
sufficient to cover us against some or all potential losses due to liability, if any, or to the expenses associated with defending against liability
claims. A product liability claim successfully asserted against us could exceed our insurance coverage, require us to use our own cash resources
and have a material adverse effect on our business, financial condition and results of operations.

         In addition, some of our licensing and other agreements with third parties require or might require us to maintain product liability
insurance. If we cannot maintain acceptable amounts of coverage on commercially reasonable terms in accordance with the terms set forth in
these agreements, the corresponding agreements would be subject to termination.

The costs of compliance with environmental, safety and similar laws could increase our cost of doing business or subject us to liability in
the event of noncompliance.

         Our business is subject to regulation under state and federal laws regarding occupational safety, laboratory practices, environmental
protection and the use, generation, manufacture, storage and disposal of hazardous substances. We may be required to incur significant costs in
the future to comply with existing or future environmental and health and safety regulations. Our research activities involve the use of
hazardous materials, chemicals and radioactive compounds. Although we believe that our procedures for handling such materials comply with
applicable state and federal regulations, we cannot eliminate the risk of contamination or injury from these materials. In the event of
contamination, we could be liable for any resulting damages, which could have a material adverse effect on our business, financial condition
and results of operations.

We are subject to intense competition that could materially impact our operating results.

          We may be unable to compete successfully against our current or future competitors. The pharmaceutical, biopharmaceutical and
biotechnology industry is characterized by intense competition and rapid and significant technological advancements. Many companies,
research institutions and universities are working in a number of areas similar to our primary fields of interest to develop new products. There
also is intense competition among companies seeking to acquire products that already are being marketed. Many of the companies with which
we compete have or are likely to have substantially greater research and product development capabilities and financial, technical, scientific,
manufacturing, marketing, distribution and other resources than at least some of our present or future strategic partners or licensees.

         As a result, these competitors may:

             ● Succeed in developing competitive products sooner than us or our strategic partners or licensees;

             ● Obtain FDA and other regulatory approvals for their products before approval of any of our products;

             ● Obtain patents that block or otherwise inhibit the development and commercialization of our drug candidates;

             ● Develop products that are safer or more effective than our products;

             ● Devote greater resources to marketing or selling their products;

             ● Introduce or adapt more quickly to new technologies or scientific advances;

             ● Introduce products that render our products obsolete;

             ● Withstand price competition more successfully than us or our strategic partners or licensees;


                                                                        11
             ● Negotiate third-party strategic alliances or licensing arrangements more effectively; or

             ● Take advantage of other opportunities more readily.

         Currently, there are three drugs approved as radiation protection agents. Amifostine (Ethyol®) is marketed by MedImmune, Inc. for
use in reduction of chemotherapy-induced kidney toxicity and radiation-induced xerostomia (damage to the salivary gland). KepivanceTM
(palifermin) is marketed by Amgen, Inc. for use in the treatment of severe oral mucositis (mouth sores) in patients with hematologic (blood)
cancers. Salagen Tablets (pilocarpine hydrochloride) is marketed by MGI Pharma in the United States as a treatment for the symptoms of
xerostomia induced by radiation therapy in head and neck cancer patients. However, there are also many companies working to develop
pharmaceuticals that act as a radiation protection agent.

Acceptance of our products in the marketplace is uncertain, and failure to achieve market acceptance will harm our business.

        Even if approved for marketing, our products may not achieve market acceptance. The degree of market acceptance will depend upon
a number of factors, including:

             ● the receipt of regulatory approvals for the indications that we are studying;

             ● the establishment and demonstration in the medical community of the safety, clinical efficacy and cost-effectiveness of our
                  products and their potential advantages over existing therapeutic products;

             ● marketing and distribution support;

             ● the introduction, market penetration and pricing strategies of competing and future products; and

             ● coverage and reimbursement policies of governmental and other third-party payors such as insurance companies, health
                  maintenance organizations and other plan administrators.

        Physicians, patients, payors or the medical community in general may be unwilling to accept, purchase, utilize or recommend any of
our products.

We may be required to make milestone payments and other payments relating to the commercialization of our products.

          Our agreements by which we acquired rights to our drug candidates provide for milestone payments by us upon the occurrence of
certain regulatory filings and approvals related to the acquired products. In the event that we successfully develop our drug candidates, these
milestone payments could be significant. In addition, our agreements require us to pay a royalty interest on worldwide sales. Also, any future
license, collaborative or other agreements we may enter into in connection with our development and commercialization activities may require
us to pay significant milestone, license and other payments in the future.

We are continually evaluating our business strategy, and may modify this strategy in light of developments in our business and other
factors.

          We continue to evaluate our business strategy and, as a result, may modify this strategy in the future. In this regard, we may, from
time to time, focus our development efforts on different drug candidates or may delay or halt the development of our drug candidates. In
addition, as a result of changes in our strategy, we may also change or refocus our existing drug discovery, development, commercialization
and manufacturing activities.

Our short-term investments, marketable securities and restricted investments, if any, are subject to certain risks which could materially
adversely affect our overall financial position.

          We invest our cash in accordance with an established internal policy and customarily in instruments which historically have been
highly liquid and carried relatively low risk. However, the capital and credit markets have been experiencing extreme volatility and disruption.
Over the past few years, the volatility and disruption have reached unprecedented levels. We maintain a portfolio of investments in short-term
investments, marketable debt securities and restricted investments, which are recorded at fair value. Certain of these transactions expose us to
credit risk in the event of default of the issuer. To minimize our exposure to credit risk, we invest in securities with strong credit ratings. Should
any of our short-term investments, marketable securities or restricted investments lose value or have their liquidity impaired, it could materially
and adversely affect our overall financial position by imperiling our ability to fund our operations and forcing us to seek additional financing
sooner than we would otherwise. Such financing may not be available on commercially attractive terms or at all.


                                                                         12
Our insurance policies are expensive and protect us only from some business risks, which could leave us exposed to significant, uninsured
liabilities.

          We do not carry insurance for all categories of risk that our business may encounter. We currently maintain general liability, property,
auto, workers’ compensation, products liability, fiduciary and directors’ and officers’ insurance policies. We do not know, however, if we will
be able to maintain existing insurance with adequate levels of coverage. For example, the premiums for our directors’ and officers’ insurance
policy have increased in the past and may increase in the future, and this type of insurance may not be available on acceptable terms or at all in
the future. Any significant uninsured liability may require us to pay substantial amounts, which would adversely affect our cash position and
results of operations.

We may have a limitation on the use of net operating loss carryforwards and tax credits.

          Our ability to utilize our net operating loss carryforwards, or NOLs, and tax credits may be limited if we undergo or have undergone
an ownership change, as defined in section 382 of the Internal Revenue Code, as a result of changes in the ownership of outstanding stock. An
ownership change generally occurs if the percentage of stock owned by one or more stockholders who own, directly or indirectly, 5% or more
of the value of our outstanding stock (or are otherwise treated as 5% stockholders under section 382 and the regulations promulgated
thereunder) has increased by more than 50 percentage points over the lowest percentage of our outstanding stock owned by these stockholders
at any time during the testing period, which is generally the three-year period preceding the potential ownership change. In the event of an
ownership change, section 382 imposes an annual limitation on the amount of post-ownership change taxable income a corporation may offset
with pre-ownership change NOLs.

         We are exposed to risks if we are unable to comply with changes to laws affecting public companies, including the Sarbanes-Oxley
Act of 2002 and the Dodd-Frank Act of 2010, and also to increased costs associated with complying with such laws.

          Laws and regulations affecting public companies in the U.S., including the provisions of the Sarbanes-Oxley Act of 2002 and the
Dodd-Frank Act of 2010, will cause us to incur increased costs as we evaluate the implications of new rules and respond to new requirements.
Delays or a failure to comply with the new laws, rules and regulations could result in enforcement actions, the assessment of other penalties
and civil suits. These laws and regulations make it more expensive for us under indemnities provided by the company to our officers and
directors and may make it more difficult for us to obtain certain types of insurance, including liability insurance for directors and officers; as
such, we may be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage.
The impact of these events could also make it more difficult for us to attract and retain qualified persons to serve on our Board of Directors, or
as executive officers. We may be required to hire additional personnel and utilize additional outside legal, accounting and advisory services —
all of which could cause our general and administrative costs to increase beyond what we currently have planned.

Our corporate compliance program cannot guarantee that we are in compliance with all potentially applicable regulations.

         The development, manufacturing, pricing, sales, coverage and reimbursement of our products, together with our general operations,
are subject to extensive regulation by federal, state and other authorities within the United States and numerous entities outside of the United
States. While we have developed and instituted a corporate compliance program based on what we believe are the current best practices,
governmental authorities may not find that our business practices comply with current or future administrative or judicial interpretations of
potentially applicable laws and regulations. If we fail to comply with any of these laws and regulations, we could be subject to a range of
regulatory actions, including suspension or termination of clinical trials, the failure to approve a product candidate, restrictions on our products
or manufacturing processes, withdrawal of products from the market, significant fines, or other sanctions or litigation.


                                                                         13
We are prohibited from taking certain actions and entering into certain transactions without the consent of certain holders of our warrants.

         As long as certain warrants issued on October 6, 2009, July 30, 2010, August 11, 2010 and December 28, 2010 are outstanding, we are
prohibited from taking certain actions or entering into certain transactions without the prior consent of the warrant holders of the warrants
issued on October 6, 2009, July 30, 2010, August 11, 2010 and December 28, 2010 (the “2009/2010 Warrant Holders”). Under these warrants,
we are also prohibited from selling the Company to an entity other than one that is publicly traded.

          Even though our Board of Directors may determine that any of these actions are in our best interest or the best interest of our
stockholders, we may be unable to complete them if we do not get the approval of the 2009/2010 Warrant Holders, who may withhold consent
to any transaction in their sole discretion. The interests of the 2009/2010 Warrant Holders may differ from those of our stockholders generally.
If we are unable to obtain consent from the 2009/2010 Warrant Holders, we may be unable to complete actions or transactions that our board of
directors determines are in the best interest of our stockholders.

Risks Related to Our Dependence on U.S. Government Grants and Contracts

Even with the BARDA Contract, we may not be able to fully fund our research and development of AEOL 10150 as a MCM for Lung-ARS.

          The BARDA Contract is a cost-plus-fixed-fee reimbursement contract that only reimburses certain specified activities that have been
previously authorized by BARDA. Additional activities may be needed and, if so, BARDA may not reimburse us for these activities.
Additionally, we have no experience meeting the significant requirements of a federal government contractor, which includes having
appropriate accounting, project tracking and earned-value management systems implemented and operational, and we may not be able to meet
these requirements in a timely way or at all. Performance under the BARDA Contract requires that we comply with appropriate regulations and
operational mandates, with which we have minimal or no operational experience. Our ability to be regularly and fully reimbursed for our
activities will depend on our ability to comply and demonstrate compliance with such requirement.

The BARDA Contract award does not guarantee that we will be successful in future clinical trials or that AEOL 10150 will be approved by
the FDA.

          The BARDA Contract provides a cost-plus-fixed-fee reimbursement opportunity for certain specified clinical and development
activities, but we remain fully responsible for conducting these activities. The award of BARDA Contract does not guarantee that any of these
activities will be successful. Our inability to be successful with certain key clinical or development activities could jeopardize our ability to
obtain Food and Drug Administration, or FDA, approval for AEOL 10150.

Most of our immediately foreseeable future revenues are contingent upon grants and contracts from the U.S. government and we may not
achieve sufficient, if any, revenues from these agreements to attain profitability.

          For the foreseeable future, we believe our main customer, if any, will be national governments, primarily the U.S. government. We
may not receive any grants from national governments. The process of obtaining government contracts is lengthy and uncertain and we will
have to compete with other companies for each contract. We may not be awarded any contracts to supply the U.S. or other governments with
our drug candidates as such awards may be made, in whole or in part, to our competitors. If the U.S. government makes significant future
contract awards for the supply to the U.S. emergency stockpile of a competing product, our business will be harmed and it is unlikely that we
will ultimately be able to supply that particular treatment or product to foreign governments or other third parties. Further, changes in
government budgets and agendas, or advances by our competitors, may result in a decreased and de-prioritized emphasis on procuring the
biodefense products we are developing.

         Due to the current economic downturn, the accompanying fall in tax revenues and the U.S. government’s efforts to stabilize the
economy, the U.S. government may be forced or choose to reduce or delay spending in the biodefense field, which could decrease the
likelihood of future government contract awards or that the government would procure products from us.

The U.S. government’s determination to award any contracts may be challenged by an interested party, such as another bidder, at the
Government Accountability Office (“GAO”) or in federal court. If such a challenge is successful, a contract may be terminated.


                                                                        14
          The laws and regulations governing procurements of goods and services by the U.S. government provide procedures by which other
bidders and other interested parties may challenge the award of a government contract. If we are awarded a government contract, such
challenges or protests could be filed even if there are not any valid legal grounds on which to base the protest. If any such protests are filed, the
government agency may decide to suspend our performance under the contract while such protests are being considered by the GAO or the
applicable federal court, thus potentially delaying delivery of goods and services and payment. In addition, we could be forced to expend
considerable funds to defend any potential award. If a protest is successful, the government may be ordered to terminate the contract and
reselect bids. The government could even be directed to award a potential contract to one of the other bidders.

Our business may become subject to audit by the U.S. government and a negative audit could adversely affect our business.

         U.S. government agencies such as the Defense Contract Audit Agency (the “DCAA”), routinely audit and investigate government
contractors. These agencies review a contractor’s performance under its contracts, cost structure and compliance with applicable laws,
regulations and standards.

          The DCAA also reviews the adequacy of, and a contractor’s compliance with, its internal control systems and policies, including the
contractor’s purchasing, property, estimating, compensation and management information systems. Any costs found to be improperly allocated
to a specific contract will not be reimbursed, while such costs already reimbursed must be refunded. If an audit uncovers improper or illegal
activities, we may be subject to civil and criminal penalties and administrative sanctions, including:

             ● termination of contracts;

             ● forfeiture of profits;

             ● suspension of payments;

             ● fines; and

             ● suspension or prohibition from conducting business with the U.S. government.

         In addition, we could suffer serious reputational harm if allegations of impropriety were made against us.

Laws and regulations affecting government contracts make it more costly and difficult for us to successfully conduct our business.

         We must comply with numerous laws and regulations relating to the formation, administration and performance of government
contracts, which can make it more difficult for us to retain our rights under these contracts. These laws and regulations affect how we conduct
business with government agencies. Among the most significant government contracting regulations that affect our business are:

             ● the Federal Acquisition Regulations, and agency-specific regulations supplemental to the Federal Acquisition Regulations,
                  which comprehensively regulate the procurement, formation, administration and performance of government contracts;

             ● the business ethics and public integrity obligations, which govern conflicts of interest and the hiring of former government
                  employees, restrict the granting of gratuities and funding of lobbying activities and incorporate other requirements such as
                  the Anti-Kickback Act and Foreign Corrupt Practices Act;

             ● export and import control laws and regulations; and

             ● laws, regulations and executive orders restricting the use and dissemination of information classified for national security
                  purposes and the exportation of certain products and technical data.


                                                                         15
         Foreign governments typically also have laws and regulations governing contracts with their respective agencies. These foreign laws
and regulations could affect how we conduct business and, in some instances, impose added costs on our business. Any changes in applicable
laws and regulations could restrict our ability to obtain contracts, which could limit our ability to conduct our business and materially adversely
affect our revenues and results of operations.

Because we depend on clinical research centers and other contractors for clinical and non-clinical testing, including testing under the
“Animal Rule”, and for certain research and development activities, the results of our clinical trial, non-clinical animal efficacy studies,
and research and development activities are largely beyond our control.

         The nature of studies, clinical trials and our business strategy of outsourcing substantially all of our research and development and
manufacturing work require that we rely on clinical research centers and other contractors to assist us with research and development, clinical
and non-clinical testing (including animal efficacy studies under the “Animal Rule”), patient enrollment and other activities. As a result, our
success depends largely on the success of these third parties in performing their responsibilities. Although we prequalify our contractors and
believe that they are fully capable of performing their contractual obligations, we cannot directly control the adequacy and timeliness of the
resources and expertise that they apply to these activities. Furthermore, we have to compete with other biodefense companies for access to this
limited pool of highly specialized resources. If our contractors do not perform their obligations in an adequate and timely manner or we are
unable to enter into contracts with them because of prior commitments to our competitors, the pace of clinical or non-clinical development,
regulatory approval and commercialization of our drug candidates could be significantly delayed and our prospects could be adversely affected.

Data obtained from clinical trials is susceptible to varying interpretations, which could delay, limit or prevent regulatory clearances.

          Data already obtained, or obtained in the future, from pre-clinical studies, non-clinical studies and clinical trials does not necessarily
predict the results that will be obtained from later pre-clinical studies and clinical trials. Moreover, pre-clinical and clinical data are susceptible
to varying interpretations, which could delay, limit or prevent regulatory approval. A number of companies in the pharmaceutical industry have
suffered significant setbacks in advanced clinical trials, even after promising results in earlier trials. The failure to adequately demonstrate the
safety and effectiveness of an intended product under development could delay or prevent regulatory clearance of the drug candidate, which
would result in delays to commercialization and could materially harm our business. Our studies and clinical trials may not demonstrate
sufficient levels of safety and efficacy necessary to obtain the requisite regulatory approvals for our drugs, and our proposed drugs may not be
approved for marketing.

          We may encounter delays or rejections based on additional government regulation from future legislation or administrative action or
changes in FDA policy during the period of development, clinical trials and FDA regulatory review. We may encounter similar delays in
foreign countries. If any of our products are approved for commercialization, sales of the products outside the U.S. would be subject to foreign
regulatory approvals that vary from country to country. The time required to obtain approvals from foreign countries may be shorter or longer
than that required for FDA approval, and requirements for foreign licensing may differ from FDA requirements. We may be unable to obtain
requisite approvals from the FDA or foreign regulatory authorities, and even if obtained, such approvals may not be on a timely basis, or they
may not cover the uses that we request.

         Even if we do ultimately receive FDA approval for any of our drug candidates, these drug candidates will be subject to extensive
ongoing regulation, including regulations governing manufacturing, labeling, packaging, testing, dispensing, prescription and procurement
quotas, record keeping, reporting, handling, shipment and disposal of any such drug. Failure to obtain and maintain required registrations or to
comply with any applicable regulations could further delay or preclude development and commercialization of our drugs and subject us to
enforcement action.

Unfavorable provisions in government contracts, some of which may be customary, may harm our business, financial condition and
operating results.

         Government contracts customarily contain provisions that give the government substantial rights and remedies, many of which are not
typically found in commercial contracts, including provisions that allow the government to:

             ● terminate existing contracts, in whole or in part, for any reason or no reason;


                                                                          16
             ● unilaterally reduce or modify contracts or subcontracts, including equitable price adjustments;

             ● cancel multi-year contracts and related orders if funds for contract performance for any subsequent year become unavailable;

             ● decline to exercise an option to renew a contract;

             ● exercise an option to purchase only the minimum amount specified in a contract;

             ● decline to exercise an option to purchase the maximum amount specified in a contract;

             ● claim rights to products, including intellectual property, developed under the contract;

             ● take actions that result in a longer development timeline than expected;

             ● audit and object to the contractor’s contract-related costs and fees, including allocated indirect costs;

             ● direct the course of a development program in a manner not chosen by the government contractor;

             ● suspend or debar the contractor from doing business with the government or a specific government agency;

             ● pursue criminal or civil remedies under the False Claims Act and False Statements Act; and

             ● control or prohibit the export of products.

         Generally, government contracts contain provisions permitting unilateral termination or modification, in whole or in part, at the
government’s convenience. Under general principles of government contracting law, if the government terminates a contract for convenience,
the terminated company may recover only its incurred or committed costs, settlement expenses and profit on work completed prior to the
termination.

          If the government terminates a contract for default, the defaulting company is entitled to recover costs incurred and associated profits
on accepted items only and may be liable for excess costs incurred by the government in procuring undelivered items from another source.
Some government contracts grant the government the right to use, for or on behalf of the U.S. government, any technologies developed by the
contractor under the government contract. If we were to develop technology under a contract with such a provision, we might not be able to
prohibit third parties, including our competitors, from using that technology in providing products and services to the government.

Risks Related to Owning Our Stock

Our principal stockholders own a significant percentage of our outstanding common stock and are, and will continue to be, able to exercise
significant influence over our affairs.

         As of May 10, 2012, Xmark Opportunity Partners, LLC (“Xmark”) possessed voting power over 39,575,839 shares, or 63.1%, of our
outstanding common stock as of such date, through its management of Goodnow Capital, L.L.C. (“Goodnow”), Xmark Opportunity Fund, L.P.,
Xmark Opportunity Fund, Ltd. and Xmark JV Investment Partners, LLC (collectively, the “Xmark Funds”), and through a voting trust
agreement by and among Biomedical Value Fund, L.P., Biomedical Value Fund, Ltd., Xmark and the Company (the “Xmark Voting Trust”)
with respect to 1,000,000 shares. As a result, Xmark is able to determine a significant part of the composition of our board of directors, holds
significant voting power with respect to matters requiring stockholder approval and is able to exercise significant influence over our operations.
The interests of Xmark may be different than the interests of other stockholders on these and other matters. This concentration of ownership
also could have the effect of delaying or preventing a change in our control or otherwise discouraging a potential acquirer from attempting to
obtain control of us, which could reduce the price of our common stock.


                                                                         17
         David Cavalier, an employee and our Chairman of the Board of Directors, is affiliated with Xmark which possesses voting power of
63.1% of our outstanding common stock as of May 10, 2012.Accordingly, Mr. Cavalier currently has, and will continue to have, a significant
influence over the outcome of all corporate actions requiring stockholder approval.

         Also as of March 19, 2012, Efficacy Capital Ltd. (“Efficacy Capital”) owned 3,724,125 shares, or 5.9%, of our outstanding common
stock as of such date, through its management of Efficacy Biotech Master Fund Ltd. As a result, Efficacy Capital is able to determine a part of
the composition of our board of directors, holds significant voting power with respect to matters requiring stockholder approval and is able to
exercise significant influence over our operations. The interests of Efficacy Capital may be different than the interests of other stockholders on
these and other matters. This concentration of ownership could also have the effect of delaying or preventing a change in our control or
otherwise discouraging a potential acquirer from attempting to obtain control of us, which could reduce the price of our common stock.

          Our executive officers and directors and holders of greater than five percent of our outstanding common stock, together with entities
that may be deemed affiliates of, or related to, such persons or entities, beneficially owned greater than 81.3% of our outstanding common
stock as of May 10, 2012. As a result, these stockholders, acting together, may be able to control our management and affairs and matters
requiring stockholder approval, including the election of directors and approval of significant corporate transactions, such as mergers,
consolidations or the sale of substantially all of our assets. The interests of our current major stockholders may not always coincide with the
interests of other stockholders and they may take actions to advance their respective interests to the detriment of other stockholders.

We may need to sell additional shares of our common stock, preferred stock or other securities to meet our capital requirements and these
future sales could cause dilution and adversely affect our stock price.

          Sales of substantial amounts of capital stock, or the perception that such sales could occur, could adversely affect the prevailing
market price of the common stock and our ability to raise capital. We may issue additional common stock in future financing transactions or as
incentive compensation for our executive management and other key personnel, consultants and advisors. Issuing any equity securities would
be dilutive to the equity interests represented by our then-outstanding shares of common stock. The market price for our common stock could
decrease as the market takes into account the dilutive effect of any of these issuances.

In the event of the conversion of our preferred stock and exercises of currently outstanding options and warrants, the ownership interests of
our current stockholders could be substantially diluted, which would reduce the market price of our common stock and could make it more
difficult for us to raise funds in the future.

         As of May 10, 2012, we had 62,670,884 shares of common stock outstanding. We may grant to our employees, directors and
consultants, options to purchase shares of our common stock under our 2004 Stock Option Plan. In addition, as of May 10, 2012, options to
purchase 9,228,233 shares were outstanding at exercise prices ranging from $0.29 to $5.10 per share, with a weighted average exercise price of
$0.72 per share, and 2,515,909 shares were reserved for issuance under the 2004 Stock Option Plan. In addition, as of May 10, 2012, warrants
to purchase 62,690,125 shares of common stock were outstanding at exercise prices ranging from $0.28 to $2.50 per share, with a weighted
exercise price of $0.31 per share.

          In connection with prior collaborations and financing transactions, we also issued 526,080 shares of Series B preferred stock and
warrants to purchase 896,037 shares of Series B preferred stock to affiliates of Elan Corporation, plc (“Elan”).These securities generally are
exercisable and convertible at the option of the Elan affiliates. The conversion of all or a portion of these securities would dilute the ownership
interests of our stockholders.

Our common stock is not listed on a national securities exchange, is illiquid and is characterized by low and/or erratic trading volume, and
the per share price of our common stock has fluctuated from $0.24 to $1.10 during the last two years.

         Our common stock is quoted on the OTC Bulletin Board under the symbol “AOLS.” An active public market for our common stock is
unlikely to develop as long as we are not listed on a national securities exchange. Even if listed, the market for our stock may be impaired
because of the limited number of investors, the significant ownership stake of Efficacy Capital and Xmark (through its management of
Goodnow and the Xmark Funds), and our small market capitalization, which is less than that authorized for investment by many institutional
investors.


                                                                        18
          Historically, the public market for our common stock has been characterized by low and/or erratic trading volume, often resulting in
price volatility. The market price of our common stock is subject to wide fluctuations due to factors that we cannot control, including the
results of preclinical and clinical testing of our products under development, decisions by collaborators regarding product development,
regulatory developments, market conditions in the pharmaceutical and biotechnology industries, future announcements concerning our
competitors, adverse developments concerning proprietary rights, public concern as to the safety or commercial value of any products and
general economic conditions.

         Furthermore, the stock market has experienced significant price and volume fluctuation unrelated to the operating performance of
particular companies. These market fluctuations can adversely affect the market price and volatility of our common stock.

If registration rights that we have previously granted are exercised, or if we grant additional registration rights in the future, the price of
our common stock may be adversely affected.

         Upon receiving notice from Xmark, we are obligated to register with the SEC shares of common stock and the common stock
underlying the warrants to purchase common stock held by the Xmark. If these securities are registered with the SEC, they may be sold in the
open market. In addition, upon receiving notice from Elan, we are obligated to register with the SEC shares of common stock underlying the
Series B preferred stock and warrants to purchase Series B preferred stock held by the Elan affiliates. If these securities are registered with the
SEC, they may be sold in the open market. We expect that we also will be required to register any securities sold in future private financings.
The sale of a significant amount of shares in the open market, or the perception that these sales may occur, could cause the trading price of our
common stock to decline or become highly volatile.

Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us, which may be beneficial to
our stockholders, more difficult and may prevent attempts by our stockholders to replace or remove our current management.

         Provisions in our amended and restated certificate of incorporation and bylaws may delay or prevent an acquisition of us or a change
in our management. These provisions include a prohibition on actions by written consent of our stockholders and the ability of our board of
directors to issue preferred stock without stockholder approval. In addition, because we are incorporated in Delaware, we are governed by the
provisions of Section 203 of the General Corporation Law of the State of Delaware, which prohibits stockholders owning in excess of 15% of
our outstanding voting stock from merging or combining with us. These provisions may frustrate or prevent any attempts by our stockholders
to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors, which
is responsible for appointing the members of our management.

We do not expect to pay cash dividends on our common stock for the foreseeable future.

         We have never paid cash dividends on our common stock and do not anticipate that any cash dividends will be paid on the common
stock for the foreseeable future. The payment of any cash dividend by us will be at the discretion of our board of directors and will depend on,
among other things, our earnings, capital, regulatory requirements and financial condition. Furthermore, the terms of some of our financing
arrangements directly limit our ability to pay cash dividends on our common stock.



                                                                        19
We may experience significant and unpredictable changes to the liability for warrants and record significant gains or losses to our
statement of operations in each period the warrants are outstanding.

          In June 2008, the Financial Accounting Standards Board (“FASB”) ratified what was originally referred to as Emerging Issues Task
Force (“EITF”) Issue No. 07-5 recently codified by FASB as Accounting Standards Codification (“ASC”) Topic 815, which contains guidance
for determining whether an Instrument (or embedded feature) is indexed to an entity’s own stock. Equity-linked instruments (or embedded
features) that otherwise meet the definition of a derivative are not accounted for as derivatives if certain criteria are met, one of which is that
the instrument (or embedded feature) must be indexed to the entity’s own stock. We adopted this guidance on October 1, 2009 and began
applying its provisions to outstanding instruments as of that date. A number of our outstanding warrants to purchase common stock are
impacted by this guidance. As a result, liability recorded for a number of our outstanding warrants may increase or decrease, sometimes
dramatically, from quarter-to-quarter. An increase in warrant liability for a period will result in a corresponding charge to our statement of
operations for such period and a decrease in warrant liability for a period will result in a corresponding gain to our statement of operations for
such period. Our outstanding warrants will continue to be revalued at each balance sheet date, which could result in significant and
unpredictable changes to our reported liabilities and significant additional gains or losses charged to the statement of operations for each period
regardless of any changes to our working capital, liquidity, or business operations.



                                                                        20
                                 SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

                                             DESCRIPTION OF THE PRIVATE PLACEMENTS

       2012 Private Placement

        On March 30, 2012 and April 4, 2012, we entered into a Securities Purchase Agreement, which we refer to as the 2012 Purchase
Agreement, with certain accredited investors to sell and issue to such investors an aggregate of approximately 2,200,166 units, which we refer
to as the 2012 Units, at a purchase price of $0.30 per unit, resulting in aggregate gross proceeds to us of approximately $660,000, we refer to
this transaction throughout the prospectus as the 2012 private placement. Each 2012 Unit consists of (i) one share of common stock and (ii) a
five year warrant to purchase 0.75 shares our common stock. The warrants in the 2012 private placement have an initial exercise price of $0.40
per share.

      One of the investors who participated in the April 4, 2012 closing of the 2012 private placement was JJK Partners, LLC whose
managing partner is Joseph Krivulka, a member of our Board of Directors. JJK Partners purchased 333,333 of the 2012 Units, resulting in
aggregate proceeds of $100,000 to us.

        In connection with the 2012 Purchase Agreement, we entered into a Registration Rights Agreement with the investors who participated
in the 2012 private placement, which we refer to as the 2012 RRA. Pursuant to the 2012 RRA, we agreed to file a registration statement with
the SEC, within 45 days from closing to register the resale of the common stock and the shares issuable upon exercise of the warrants issued in
the 2012 private placement (collectively, the “2012 Registrable Securities”). We also agreed to use our best efforts to have the registration
statement declared effective as promptly as possible after the filing thereof, but in any event within 120 days (180 days if the we receive
comments from the SEC) from the filing date. We agreed to keep the registration statement continuously effective until the earlier to occur of
(i) the date after which all of the 2012 Registrable Securities registered thereunder have been sold and (ii) the date on which all of the 2012
Registrable Securities covered by the registration statement may be sold without volume restrictions pursuant to Rule 144 under the Securities
Act.

       In the event (i) the registration statement has not been filed by the agreed upon filing date, (ii) an acceleration request has not been filed
within five trading days of the date which we are notified that the registration statement will not be reviewed by the SEC staff or is not subject
to further review and comment by the SEC staff, (iii) the registration statement has not been declared effective by the required effectiveness
date, or (iv) sales cannot be made pursuant to such registration statement for any reason (other than by reason of a permissible delay under the
terms of the 2012 RRA) after the registration statement has been declared effective by the SEC (each such event, a “Registration Default”),
then we have agreed to pay each of the investors as liquidated damages an amount equal to 0.5% of the purchase price paid by each such
investor with respect to any Registrable Securities then held and not registered pursuant to an effective registration statement, per each 30-day
period or portion thereof during which the Registration Default remains uncured thereafter. However, liquidated damages, if any, payable as a
result of any Registration Default shall cease to accrue, in any event, after the date that is six (6) months after the closing.

      We granted the investors in the 2012 private placement customary indemnification rights in connection with the registration
statement. These investors have also granted us customary indemnification rights in connection with the registration statement.

       The foregoing description of the 2012 private placement does not purport to be complete and is qualified in its entirety by reference to
the Form of Securities Purchase Agreement, the Form of 2012 RRA and the Form of warrant, copies of which are attached as Exhibits 10.1,
10.2 and 10.3, respectively, to the Form 8-K we filed with the SEC on April 4, 2012.

       2010 Private Placement

       On August 11, 2010, we entered into a Securities Purchase Agreement, which we refer to as the 2010 Purchase Agreement, with two
accredited institutional investors pursuant to which the Company sold and issued to such investors in a private placement an aggregate of
2,500,000 units, which we refer to as the 2010 Units, which units are comprised of an aggregate of 2,500,000 shares of common stock of the
Company and warrants to purchase up to an aggregate of 1,875,000 additional shares of common stock, which we refer to as the 2010
Warrants. Each 2010 Unit represents one share of common stock and a warrant to purchase 0.75 of one share of common stock, at a purchase
price of $0.40 per unit for aggregate gross proceeds of $1,000,000; we refer to this transaction throughout this prospectus as the 2010 private
placement. The 2010 Warrants are exercisable for a seven-year period from their date of issuance; have an initial exercise price of $0.50 per
share subject to adjustment pursuant to the 2010 Warrants; contain a “cashless exercise” feature that allows the holder to exercise the Warrants
without a cash payment to the Company under certain circumstances; contain a dividend participation right which allows the holder to receive
any cash dividends paid on the Common Stock without exercising the Warrant; contain a provision that provides for the reduction of the
exercise price to $0.01 in the event of any payment of cash dividends by us or upon a change of control; and contain anti-dilution provisions in
the event of a stock dividend or split, dividend payment or other issuance, reorganization, recapitalization or similar event. The 2010 Warrants
are subject to an issuance limitation that prevents the holder of the warrants from exercising the warrants if the holder would beneficially own
more than 9.99% of the shares of Common Stock then issued and outstanding, which such limitation cannot be modified by the holder before
the sixty-first day after notice to the Company of the holder’s intention to waive the issuance limitation.

      The net proceeds to us from the 2010 private placement, after deducting for expenses, were approximately $900,000.

       We also granted to the investors in the 2010 private placement the option to acquire, collectively, up to 2,500,000 additional 2010 Units,
comprised of an aggregate of 2,500,000 shares of common stock of the Company and warrants to purchase up to an aggregate of 1,875,000
additional shares of common stock at a per unit purchase price of $0.40, which we refer to as the 2010 Call Option. In addition, the investors in
the 2010 private placement granted to us the option to require these investors, severally and not jointly, to acquire up to 2,500,000 additional
2010 Units, less any additional 2010 Units acquired under the 2010 Call Option, at the per unit purchase price of $0.40, which we refer to as
the 2010 Put Option.

      On December 28, 2010, the investors exercised their 2010 Call Option and we received $1,000,000 in proceeds in exchange for
2,500,000 common shares and 1,875,000 additional 2010 Warrants, with an initial exercise price of $0.50 per share, subject to adjustment as
provided in the warrants. The net cash proceeds to us from the exercise of the 2010 Call Option, after deducting for expenses, were
approximately $990,000.

       In connection with the 2010 private placement, the Company also entered into a Registration Rights Agreement with the Investors,
which we refer to as the 2010 RRA. Pursuant to the 2010 RRA, the Company agreed to file one or more registration statements with the SEC
covering the resale of the shares of common stock issued as part of the 2010 Units and all shares of common stock issuable upon exercise of the
2010 Warrants (the “2010 Registrable Securities”) upon demand of the holders of a majority of the 2010 Registrable Securities. Pursuant to the
2010 RRA, we also granted the Investors certain piggyback registration rights, pursuant to which the investors in the 2010 private placement
have elected to include the securities they acquired in this registration statement. The Company also agreed to use its commercially reasonable
efforts to keep the registration statements effective for a specified period.

        Affiliates of Xmark were the sole investors in the 2010 private placement. Together with its affiliates, Xmark beneficially owned
approximately 67.5% of the Company's outstanding common stock prior to the 2010 private placement. Xmark is the sole manager of
Goodnow and possesses sole power to vote and direct the disposition of all securities of the Company held by Goodnow. Goodnow has the
right to designate up to two directors for election to the Company's Board of Directors pursuant to the terms of a purchase agreement between
Goodnow and the Company. David C. Cavalier, a current director of the Company, is President of Goodnow.

       The foregoing description of the 2010 private placement does not purport to be complete and is qualified in its entirety by reference to
the 2010 RRA, 2010 Purchase Agreement, and 2010 Warrants attached as exhibits 4.1, 10.1 and 10.2, respectively, to the Form 8-K we filed
with the SEC on August 12, 2010.

      2009 Private Placement and conversion

       On October 6, 2009, we entered into a Securities Purchase and Exchange Agreement, which we refer to as the 2009 Purchase
Agreement, with several accredited institutional investors pursuant to which we sold and issued to the investors in a private placement an
aggregate of 5,892,857 units, which we refer to as the 2009 Units, comprised of an aggregate of 5,892,857 shares of our common stock and
warrants to purchase up to an aggregate of 11,785,714 additional shares of Common, which we refer to as the 2009 Warrants, with an initial
exercise price of $0.28 per share, subject to adjustment pursuant to the 2009 Warrants. Each 2009 Unit represents one share of common stock
and a 2009 Warrant to purchase two shares of common stock, at a purchase price of $0.28 per Unit for aggregate gross proceeds of $1,650,000,
we refer to this transaction throughout the prospectus as the 2009 private placement. The 2009 Warrants are exercisable for a seven year period
from their date of issuance; contain a “cashless exercise” feature that allows the holder to exercise the 2009 Warrants without a cash payment
to the Company under certain circumstances; contain a dividend participation right which allows the holder to receive any cash dividends paid
on the Common Stock without exercising the 2009 Warrant and contain a provision that provides for the reduction of the exercise price to
$0.01 in the event of any such payment of cash dividends by the Company or upon a change of control and contain anti-dilution provisions in
the event of a stock dividend or split, dividend payment or other issuance, reorganization, recapitalization or similar event. The 2009 Warrants
are subject to an issuance limitation that prevents the holder of the warrants from exercising the warrants if the holder would beneficially own
more than 9.99% of the shares of Common Stock then issued and outstanding, which such limitation cannot be modified by the holder before
the sixty-first day after notice to the Company of the holder’s intention to waive the issuance limitation.


                                                                       23
      The net proceeds to us from the 2009 private placement, after deducting for expenses, were approximately $1.5 million.

       We also granted to the investors in the 2009 private placement the option to acquire, collectively, up to an additional 5,892,857
additional 2009 Units, comprised of an aggregate of 5,892,857 shares of common stock and warrants to purchase up to an aggregate of
11,785,714 additional shares of common stock at the per Additional Unit purchase price of $0.28, which we refer to as the 2009 Call Option. In
addition, the Investors granted to us the option to require these investors, severally and not jointly, to acquire up to 5,892,857 additional 2009
Units, less any 2009 Units acquired under the 2009 Call Option, at the per unit purchase price of $0.28, which we refer to as the 2009 Put
Option.

      On July 30, 2010, the Company exercised the 2009 Put Option. As a result of the exercise, the Company received $1.65 million in gross
proceeds from the investors in exchange for 5,892,857 additional 2009 Units, comprised of an aggregate of 5,892,857 shares of common stock
and warrants to purchase up to an aggregate of 11,785,714 additional shares of common stock at a purchase price of $0.28 per share.

       In addition, the investors agreed to convert all $1,000,000 of the Company’s Senior Convertible Notes issued in 2008, which we refer to
as the 2008 Notes into common stock at a conversion rate of $0.35 per share, resulting in the issuance to the investors of 2,857,143 shares of
common stock, which we refer to as the Conversion Shares, and to exchange their remaining option to purchase an additional $4,000,000 in
Senior Convertible Notes for warrants to purchase up to 14,285,714 shares of Common Stock in substantially the same of form and terms of the
2009 Warrants issued in the 2009 private placement, including an initial exercise price of $0.28 per share, subject to adjustment pursuant to the
warrants, which we refer to as the Note Warrants. As consideration for the investors to convert the 2008 Notes, the Company agreed to
exchange warrants to purchase up to 2,000,000 shares of Common Stock issued to the investors in connection with the sale of the 2008 Notes,
warrants to purchase up to 2,150,000 shares of Common Stock issued to the investors and one of their affiliates in connection with a financing
completed in November 2005 and warrants to purchase up to 13,392,857 shares of Common Stock issued to the Investors in connection with a
financing completed in March 2009 in exchange for warrants to purchase up to 17,542,857 shares of Common Stock in substantially the same
form and terms of the 2009 Warrants issued in the 2009 private placement, including an initial exercise price of $0.28 per share, subject to
adjustment pursuant to the warrants, we refer to these warrants as the Exchange Warrants. We refer to the series of transactions described in
this paragraph collectively as the conversion.

       On December 24, 2009, the Company entered into an amendment to the 2009 Purchase Agreement, which we refer to as the Purchase
Agreement Amendment, pursuant to which the Company agreed to lower the conversion price of the 2008 Notes from $0.35 per share to $0.28
per share and as a result, issued to the investors in the 2009 private placement an additional 714,286 shares of the Company’s common stock
upon conversion of the 2008 Notes. The Purchase Agreement Amendment was executed to resolve a misunderstanding regarding one of the
financing terms between the investors and us. The Company did not receive any proceeds from the issuance of additional shares.

        In connection with the 2009 private placement and the conversion, we also entered into a Registration Rights Agreement, which we refer
to as the 2009 RRA, with the investors. Pursuant to the 2009 RRA, we agreed to file one or more registration statements with the SEC
covering the resale of the shares issued in the 2009 private placement, the Conversion Shares, 5,357,143 shares of common stock issued to the
same investors in a previous private placement that closed in March 30, 2009 and all shares of common stock issuable upon exercise of the
2009 Warrants, the Note Warrants and the Exchange Warrants (collectively, the “2009 Registrable Securities”) upon demand of the holders of
a majority of the 2009 Registrable Securities. The Company also agreed to use its commercially reasonable efforts to keep the Registration
Statements effective for a specified period.

       Affiliates of Xmark were the sole investors in the 2009 private placement and, together with the Company, were the sole participants in
the Conversion. Together with its affiliates, Xmark beneficially owned approximately 55% of the Company's outstanding common stock prior
to the 2009 private placement and the Conversion. As disclosed above, Xmark Opportunity Partners, LLC is the sole manager of Goodnow.
and possesses sole power to vote and direct the disposition of all securities of the Company held by Goodnow. Goodnow has the right to
designate up to two directors for election to the Company's Board of Directors pursuant to the terms of a purchase agreement between
Goodnow and the Company. David C. Cavalier, a current director of the Company, is President of Goodnow.


                                                                       24
       The foregoing description of the 2009 private placement and conversion does not purport to be complete and is qualified in its entirety
by reference to the 2009 RRA, 2009 Purchase Agreement and 2009 Warrants attached as exhibits 4.1, 10.1 and 10.2, respectively, to the Form
8-K we filed with the SEC on October 6, 2009 and by reference to the Purchase Agreement Amendment attached as exhibit 10.1 to the Form
8-K we filed with the SEC on December 28, 2009.

      Each of the private placements noted above were made in reliance on Section 4(2) of the Securities Act, and Rule 506 promulgated
thereunder. The investors who participated in these three private placements and the associated conversions and secondary closings, as the case
may be, are referred to throughout this prospectus as the selling stockholders.




                                                                      25
                                                            USE OF PROCEEDS

          All proceeds from the sale of our common stock covered by this prospectus will belong to the selling stockholders who offer and sell
their shares. We will not receive any proceeds from the sale of the common stock by the selling stockholders. A portion of the shares covered
by this prospectus are issuable upon exercise of warrants to purchase our common stock. Upon any exercise of the warrants for cash, the selling
stockholders would pay us the exercise price of the warrants. Under certain conditions set forth in the warrants, the warrants are exercisable on
a cashless basis. If any warrants are exercised on a cashless basis, we would not receive any cash payment from the selling stockholders upon
any exercise of such warrants.




                                                                       26
                                                 DETERMINATION OF OFFERING PRICE

             This offering is being made solely to allow the selling stockholders to offer and sell shares of common stock to the public. The
selling stockholders may offer for resale some or all of their shares at the time and price that they choose. On any given day, the price per share
is likely to be based on the quoted price for the common stock on the OTC Bulletin Board on the date of sale, unless shares are sold in private
transactions. Consequently, we cannot currently make a determination of the price at which shares offered for resale pursuant to this prospectus
may be sold.




                                                                        27

On May 10, 2012, the last reported sales price of our common stock on the OTC Bulletin Board was $0.31 per share.

Approximate Number of Equity Security Holders

As of May 10, 2012 the number of record holders of our common stock was 91, and we estimate that the number of beneficial owners was
approximately 3,000.

Dividend Policy

     We have never paid a cash dividend on our common stock and we do not anticipate paying cash dividends on our common stock in the
foreseeable future. If we pay a cash dividend on our common stock, we also must pay the same dividend on an as converted basis on our Series
B preferred stock. In addition, under the terms of the warrants to purchase up to 59,149,999 shares of our common stock issued to Xmark in
four transactions (on each of October 6, 2009, July 30, 2010, August 11, 2010 and December 28, 2010), if we were to pay a dividend on our
common stock, the exercise price of these warrants would be reset from $0.28 per share or $0.50 per share, as applicable, to $0.01 per share
and the warrant holders would also be entitled to receive any such dividend paid.

    Moreover, any additional preferred stock to be issued and any future credit facilities might contain restrictions on our ability to declare and
pay dividends on our common stock. We plan to retain all earnings, if any, for the foreseeable future for use in the operation of our business
and to fund future growth.

including those discussed under “Risk Factors” and elsewhere in this prospectus.

Operations Summary

      Business

       Aeolus Pharmaceuticals, Inc. is a biopharmaceutical company that is developing a platform of a new class of broad-spectrum, catalytic
antioxidant compounds based on technology discovered at Duke University and National Jewish Health. These compounds, known as
metalloporphyrins, scavenge reactive oxygen species (“ROS”) at the cellular level, mimicking the effect of the body’s own natural antioxidant
enzyme, superoxide dismutase. While the benefits of antioxidants in reducing oxidative stress are well-known, research with our compounds
indicates that metalloporphyrins can be used to affect signaling via ROS at the cellular level as well. In addition, there is evidence that
high-levels of ROS can affect gene expression and this may be modulated through the use of metalloporphyrins. We believe this could have a
profound beneficial impact on people who have been exposed, or are about to be exposed, to high-doses of radiation, whether from cancer
therapy or a nuclear event.

       Our lead compound, AEOL 10150, is a metalloporphyrin specifically designed to neutralize reactive oxygen and nitrogen species. The
neutralization of these species reduces oxidative stress, inflammation, and subsequent tissue damage-signaling cascades resulting from
radiation exposure. We are developing AEOL 10150 as a medical countermeasure against the pulmonary effects of radiation exposure under a
contract valued at up to $118.4 million with BARDA a division of the Department of Health and Human Services. Additionally, we receive
development support from the National Institutes of Health for development of the compound as a medical countermeasure against radiation
and chemical exposure.

       We are leveraging the significant investment made by U.S. government agencies to develop this promising compound for use in
oncology indications, where it would be used in combination with radiation and chemotherapy. Data have been published showing that AEOL
10150 not only does not interfere with the therapeutic benefit of radiation therapy in prostate and lung cancer preclinical studies, but also helps
increase tumor control when used in combination with radiation and chemotherapy. Oxidative stress is a more potent stabilizer of the
pro-angiogenic transcription factor, HIF-1a, than hypoxia (Dewhirst et al., Cycling hypoxia and free radicals regulate angiogenesis and
radiotherapy response, Nature Reviews, Volume 8, June 2008). By reducing oxidative stress, AEOL10150 suppresses HIF-1a stabilization,
thereby improving tumor vascularization and tissue oxygenation. Poorly perfused/oxygenated tumor tissue is resistant to radiation as oxygen is
required for radiation-induced cell kill. Thus, by improving tumor oxygenation, AEOL10150 improves impact of radiation on
tumors. Radiotherapy is a key therapy in non-small cell lung cancer. It is the treatment of choice for patients with unresectable Stage I-II
disease, and is recommended, in combination with chemotherapy, for patients with unresectable stage IIIB disease. (Pipeline Insight: Cancer
Overview – Lung, Brain, Head and Neck, Thyroid; Datamonitor 2008, 37.)

       AEOL 10150 is also currently being developed as a medical countermeasure for gastrointestinal sub-syndrome of acute radiation
syndrome (“GI-ARS”) and pulmonary sub-syndrome of acute radiation syndrome (“Lung-ARS”), both of which are caused by exposure to
radiation due to a radiological or nuclear event. To date, the GI-ARS development program has been funded by the NIH – National Institute of
Allergy and Infectious Diseases (“NIAID”) through programs at the University of Maryland and Epistem, Ltd. Until February 2011, the
Lung-ARS program was principally funded by us and the work was performed at Duke University and the University of Maryland. Since
February 11, 2011, the Lung-ARS program has been funded by BARDA.

       On February 11, 2011, we signed the BARDA Contract with BARDA, pursuant to which we will receive $10.4 million from BARDA in
the base period of performance and up to an additional $108 million in options exercisable over four years following the base period of
performance, if the options are exercised by BARDA for a contract value of $118.4 million. On April 16, 2012, we announced that BARDA
had exercised two contract options worth approximately $9.1 million. The bulk of the options are for the period of performance beginning
April 1, 2012 and ending March 31, 2013.


                                                                        29
      NIAID’s Radiation/Nuclear Medical Countermeasures development program is currently testing AEOL 10150 as a countermeasure for
GI-ARS caused by exposure to high levels of radiation due to a radiological or nuclear event. Similarly, the NIH’s Countermeasures Against
Chemical Threats (“CounterACT”) program has tested, and continues to test, AEOL 10150 as a medical countermeasure for exposure to
chemical vesicants such as chlorine gas, phosgene gas, mustard gas and nerve agents.

       AEOL 10150 has already performed well in animal safety studies, been well-tolerated in two human clinical trials, demonstrated
efficacy in two species in acute radiation syndrome (“ARS”) studies and demonstrated statistically significant survival efficacy in an acute
radiation-induced lung injury model. AEOL 10150 has also demonstrated efficacy in validated animal models for GI-ARS, chlorine gas
exposure, and sulfur mustard gas exposure. Efficacy has been demonstrated in Lung-ARS in both rodent and non-human primate studies
(“NHP”), with AEOL 10150 treated groups showing significantly reduced weight loss, inflammation, oxidative stress, lung damage, and most
importantly, mortality. Therapeutic efficacy was demonstrated when delivered after exposure to radiation (24 hours after exposure for mice in
the GI-ARS study and NHPs in the Lung-ARS studies, and two hours after exposure for mice in the Lung-ARS studies).

      We have an active Investigational New Drug Application (“IND”) on file with the FDA for AEOL 10150 as a potential treatment for
amyotrophic lateral sclerosis (“ALS”). We plan to file an IND for cancer with the oncology division of the FDA as well as with the Division of
Medical Imaging Products for Lung-ARS. Extensive toxicology and pharmacology packages are already in place. We have already completed
two Phase 1 safety studies in 50 humans demonstrating the drug to be safe and well tolerated. Chemistry, Manufacturing, and Controls work
has been completed, and pilot lots have been prepared for scaling-up. At the current time, we have no plans to conduct further clinical trials in
ALS.

       We have two programs underway for the development of our second drug candidate, AEOL 11207, for the treatment of epilepsy and
Parkinson’s disease. These programs are being funded, in part, by private foundations, including the Michael J. Fox Foundation and Citizens
United for Research in Epilepsy (“CURE”), and government grants. In February 2011 data were published in the Journal Neurobiology of
Disease from the CURE study indicating AEOL 11207 significantly reduced both the frequency and duration of spontaneous seizures in
a pre-clinical epilepsy model. Additionally, the study showed an increase in average life span, protection against neuronal death and no
difference in seizure severity.

      BARDA Contract

      In December 2009, we were informed by BARDA that we had been chosen to submit a full proposal for funding of our Lung-ARS
program from its current stage through FDA approval, based on a summary “white paper” submitted by us earlier in 2009. We submitted a full
proposal in February 2010. We were notified in July 2010 that our proposal had been chosen by BARDA, and then entered into negotiations for
a development contract with the agency.

        On February 11, 2011, we entered into the BARDA Contract. Pursuant to the BARDA Contract, we will receive $10.4 million in the
first year base period of performance and up to an additional $108 million in options over four years, if the options are exercised by BARDA,
for a total contract value of $118.4 million. The base period of performance was from February 11, 2011 to February 10, 2012 and we
recognized an aggregate of $2.2 million of the $10.4 million base period performance fee from BARDA in the quarter ended December 31,
2011 and a total of $7.0 million through December 31, 2011. Each additional option, if exercised by BARDA following our completion of
specific tasks set forth in the BARDA Contract, would extend the period of performance by an additional period. If all options are exercised,
the period of performance would continue through February 10, 2016.

       Activities conducted or to be conducted during the base period of performance include radiation survival curve studies, dosing studies,
bulk drug manufacturing, final drug product manufacturing, validation testing, compliance studies and the filing of IND, an orphan drug status
application and a fast track designation application with the FDA. In the event BARDA exercises one or more of the options to extend the term
of the BARDA Contract, optional activities to be conducted would include, among other things, bulk drug and final drug product
manufacturing, stability studies, animal pivotal efficacy studies, human clinical safety studies and Phase I, Phase II and pre-new drug
application (“NDA”) meetings and applications with the FDA.

       Following the commencement of the BARDA Contract, we entered into a series of agreements with various parties in furtherance of our
efforts under the BARDA Contract, which are described in this paragraph. On February 18, 2011, we entered into a Research and
Manufacturing Agreement with Johnson Matthey Pharmaceutical Materials, Inc. (d/b/a Johnson Matthey Pharma Services) (“JMPS”), pursuant
to which we engaged JMPS to, among other things, assess and develop a reliable separations or manufacturing process for certain chemical
compounds as required by us and to perform such additional work as may be required or agreed upon by the parties and to manufacture
compounds for us. Each project performed by JMPS under the agreement will have a detailed project description and separate fee agreement
based on the nature and duration of the project and the specific services to be performed by JMPS. The term of the agreement with JMPS will
continue until February 16, 2016 or the date on which all projects under the agreement have been completed or terminated. On February 23,
2011, we and Booz Allen Hamilton Inc. (“Booz Allen”) entered into a General Management Consulting Assignment, pursuant to which we
engaged Booz Allen to, among other things, provide us with evaluation, operational and transitional support during the establishment and
enhancement of our quality assurance, document management, earned value management and program management systems. We have agreed
to pay Booz Allen on a time-and-materials basis. On March 16, 2011, we and the Office of Research and Development of the University of
Maryland, Baltimore (“UMB”) entered into a Sub-award Agreement, pursuant to which we engaged UMB to, among other things, develop a
whole thorax lung irradiation model for use in studies supporting the licensure of AEOL 10150. The Sub-award Agreement is a fixed fee
agreement inclusive of all direct and indirect costs. As a result of the contract modification and no-cost extension with BARDA mentioned
below, the term of the Sub-award Agreement will continue through September, 2012. On April 12, 2011, we and Duke University (“Duke”)
entered into a Sponsored Research Agreement (Non-Clinical), pursuant to which we engaged Duke to perform a program of scientific research
entitled “Murine Studies for the Development of AEOL 10150 as a Medical Countermeasure Against ARS and DEARE” (Delayed Effects of
Acute Radiation Exposure), which will include, among other things, studies and models of optimum dosing of AEOL 10150 in mice. We
entered into the Sponsored Research Agreement in furtherance of our efforts under the BARDA Contract. The Sponsored Research Agreement
is a cost plus fee agreement inclusive of all direct and indirect costs.


                                                                   30
       On February 14, 2012, the Aeolus team presented the results and deliverables that had been produced during the first twelve months
under the base period of the BARDA Contract at an "In-Progress Review" meeting with BARDA, and requested the exercise of additional
contract options, which contain the key items required in the advanced development of AEOL 10150 from April 2012 through March 2013.

       On February 15, 2012, we announced that we entered into a contract modification and no-cost extension with the BARDA. The
modification and extension allowed us to continue operating under the base period of the contract awarded in February 2011, and restructured
the timing and components of the options that could be awarded under the remaining four years of the agreement. The changes did not impact
the total potential value of the contract, which remains at approximately $118 million. The contract restructure was driven by our ability to
generate cost savings in the base year contract, and to allow BARDA to better manage contract options to expedite development program.

       On April 16, 2012, we announced that BARDA had exercised two contract options worth approximately $9.1 million. The bulk of the
options are for the period of performance beginning April 1, 2012 and ending March 31, 2013. BARDA's exercise of the options was in
response to the presentation of the deliverables and progress made under the contract at the meeting on February 14, 2012. Among the key
items in the options BARDA exercised are animal efficacy studies, mechanism of action research and manufacturing and process validation
work. All of these items build off of work successfully completed during the first twelve months of the contract base period. The contract is
designed to produce the data necessary for an approval under the FDA "Animal Rule" and for a potential Emergency Use Authorization (EUA).
An approval or EUA would allow the federal government to buy AEOL 10150 for the Strategic National Stockpile under Project Bioshield.
Project Bioshield is designed to accelerate the research, development, purchase and availability of effective medical countermeasures for the
Strategic National Stockpile

       Since February 11, 2011, we have been actively developing AEOL 10150 under the BARDA Contract. Among the key deliverables
accomplished in the program, we hired the necessary personnel required under the contract, initiated the radiation dose studies in mice and
NHPs, manufactured a GMP batch for use in human safety studies and a non-GMP batch of material for use in animal efficacy studies,
developed significant improvements to the process for manufacturing compound which will reduce the cost of producing the drug; made
several discoveries related to the mechanism of damage of radiation and mechanism of action of AEOL 10150; met with the FDA to discuss
our IND filing for Lung-ARS; and designed and initiated quality, reporting, risk management and project management programs required under
the BARDA Contract.

       According to the BARDA Contract, we plan to file an Emergency Use Authorization (“EUA”) with the FDA in approximately July
2013. An EUA is a legal means for the FDA to approve new drugs or new indications for previously approved drugs that may be stockpiled
and used during a declared emergency. To date, about half of the procurements for the national stockpile for medical countermeasures against
potential terrorist events have been made under EUAs, prior to approval by the FDA for the indication in question.

      Duke Licenses


                                                                     31
       Pursuant to our license agreements with Duke University (“Duke”), we have obtained exclusive worldwide rights from Duke to products
using antioxidant technology and compounds developed by Dr. Irwin Fridovich and other scientists at Duke. We are obligated under the
licenses to pay Duke royalties ranging in the low single digits of net product sales during the term of the Duke licenses, and we must make
payments upon the occurrence of certain development milestones in an aggregate amount of up to $2,000,000. In addition, we are obligated
under the Duke licenses to pay patent filing, prosecution, maintenance and defense costs. The Duke licenses are terminable by Duke in the
event of breach by us and otherwise expire when the last licensed patent expires.

      National Jewish Medical and Research Center License

      We have obtained an exclusive worldwide license from the NJMRC to develop, make, use and sell products using proprietary
information and technology developed under a previous Sponsored Research Agreement within the field of antioxidant compounds and related
discoveries. We must make milestone payments to the NJMRC in an aggregate amount of up to $250,000 upon the occurrence of certain
development milestones. Our royalty payment obligations to the NJMRC under this license agreement are in the low single digits of net
product sales. We are also obligated to pay patent filing, prosecution, maintenance and defense costs. This NJMRC license agreement is
terminable by the NJMRC in the event of breach and otherwise expires when the last licensed patent expires.

      National Jewish Health License

       In 2009, we obtained an additional exclusive worldwide license from National Jewish Health (“NJH”) to develop, make, use and sell
products using proprietary information and technology developed at NJH related to certain compounds as a medical countermeasure against
mustard gas exposure. Under this license agreement, we must make milestone payments to NJH in an aggregate amount of up to $500,000
upon the occurrence of certain development milestones. In addition, we must make royalty payments to NJH under this license agreement
ranging in the low-single digits as a percentage of all sublicensing fees, milestone payments and sublicense royalties that we receive from
sublicenses granted by us pursuant to this license agreement. We are also obligated to pay patent filing, prosecution, maintenance and defense
costs. This NJH license agreement is terminable by NJH in the event of breach and otherwise expires when the last licensed patent expires

        Our lead compound, AEOL 10150, is expected to enter human clinical trials in oncology, where it will be used in combination with
radiation therapy. AEOL 10150 has previously been tested in two Phase I clinical trials with no serious adverse events reported. The compound
is also being developed as a medical countermeasure against Lung-ARS as well as GI-ARS, both caused by exposure to radiation due to a
radiological or nuclear event. It is also being developed for use as a countermeasure for exposure to chemical vesicants such as chlorine gas and
sulfur mustard gas. AEOL 10150 has already performed well in animal efficacy and safety studies in each of these potential indications. A
significant portion of the funding for the medical countermeasure development programs to date has come from various government entities.
Although we expect this funding to continue, there is no guarantee that it will.

       We do not generate revenue from sales, only from development contracts and grants from the U.S. government. Therefore, we must rely
on public or private equity offerings, debt financings, collaboration arrangements or grants to finance our operations. Our strategy is to use
non-dilutive capital wherever possible to develop our platform of broad-spectrum catalytic antioxidant compounds in important unmet
indications of national strategic importance. We plan to continue to leverage such capital, like the investments made by U.S. government
agencies, such as the NIAID’s and NIH’s CounterACT program, in AEOL 10150 as a medical countermeasure, to concurrently develop these
promising compounds for use in significant unmet medical indications, like oncology. We are currently leveraging such non-dilutive
capital with AEOL 10150, where we are developing the compound as a medical countermeasure against the pulmonary sub-syndrome of acute
radiation syndrome under the BARDA Contract. We recognized $2.2 million in revenue during the quarter ended December 31, 2011 related to
the BARDA Contract.

Results of Operations

Three months ended March 31, 2012 versus three months ended March 31, 2011

      We had net income of $2,763,000 (including a non-cash adjustment for decreases in valuation of warrants of $3,324,000) and net
income of $3,778,000 (including a non-cash charge for decreases in valuation of warrants of $4,746,000), and cash outflows from operations of
$1,181,000 and cash outflows from operations of $1,408,000 for the three months ended March 31, 2012 and March 31, 2011, respectively.


                                                                       32
      Revenue for the three months ended March 31, 2012 was $2,231,000, which compares to $785,000 in revenue for the three months
ended March 31, 2011. The increase is primarily attributable to a full three months of activity and an increased level of development work in
progress under the BARDA Contract as of March 31, 2012 compared with less than two months of activity and a decreased level of
development before to the inception of the BARDA Contract during the three months ended March 31, 2011.

      Research and Development

       Research and Development (“R&D”) expenses increased $1,020,000, or 112%, to $1,927,000 for the three months ended March 31,
2012 from $907,000 for the three months ended March 31, 2011. The increase is primarily attributable to work related to the BARDA
Contract. R&D expenses for our antioxidant program have totaled $46,253,000 from inception through March 31, 2012. We currently have ten
development programs in progress: studies of AEOL 10150 as a medical countermeasure against the effects of sulfur mustard gas, phosgene
gas and chlorine gas on the lungs, against the effects of radiation on the lungs and on the gastro-intestinal tract, against the effects of nerve
agents, and as a treatment for cancer, studies of AEOL 11207 and several other compounds as potential treatments for Parkinson’s disease and
epilepsy, and a study of Hexyl as protectant against radiation exposure. Because of the uncertainty of our research and development and
clinical studies, we are unable to predict the total level of spending on the program or the program completion date. We expect R&D expenses
during fiscal year 2012 will be higher than fiscal year 2011 because we expect to continue and expand our efforts under the BARDA Contract.
However, we anticipate that much of the increase in R&D spending should be reimbursed under that contract.

      General and Administrative

       General and administrative (“G&A”) expenses increased $25,000, or 3%, to $865,000 for the three months ended March 31, 2012 from
$840,000 for the three months ended March 31, 2011. Salaries and wages and increased by $126,000 due to three full months of activity with
our increased staff under the BARDA Contract as of March 31, 2012 compared to less than two months of activity with our increased staff
under the BARDA Contract for three months ended March 31, 2011.

Six months ended March 31, 2012 versus six months ended March 31, 2011

       We had net income of $5,740,000 (including a non-cash adjustment for decreases in valuation of warrants of $7,012,000) and net losses
of $3,842,000 (including a non-cash charge for increases in valuation of warrants of $2,456,000), and cash outflows from operations of
$513,000 and cash outflows from operations of $1,925,000 for the six months ended March 31, 2012 and March 31, 2011, respectively.

       Revenue for the six months ended March 31, 2012 was $4,446,000, which compares to $785,000 revenue for the six months ended
March 31, 2011. The increase is primarily attributable to a full six months of activity and an increased level of development work in progress
under the BARDA Contract as of March 31, 2012 compared with less than two months of activity and a decreased level of development due to
the inception of the BARDA Contract during the six months ended March 31, 2011.

      Research and Development

       Research and Development (“R&D”) expenses increased $2,900,000, or 264%, to $3,998,000 for the six months ended March 31, 2012
from $1,097,000 for the six months ended March 31, 2011. The increase is primarily attributable to a full six months of activity and an
increased level of development work in progress under the BARDA Contract as of March 31, 2012 compared with less than two months of
activity and a decreased level of development prior to the inception of the BARDA Contract during the six months ended March 31, 2011.

      General and Administrative

       General and administrative (“G&A”) expenses increased $330,000, or 24%, to $1,720,000 for the six months ended March 31, 2012
from $1,390,000 for the six months ended March 31, 2011. Salaries and wages and increased by $360,000 due to six full months of activity
with our increased staff under the BARDA Contract as of March 31, 2012 compared to less than two months of activity with our increased staff
under the BARDA Contract for six months ended March 31, 2011.

Fiscal Year Ended September 30, 2011 Compared to Fiscal Year Ended September 30, 2010


                                                                       33
       We had net income of $299,000 (including a non-cash adjustment for decreases in valuation of warrants of approximately $3,887,000)
for the fiscal year ended September 30, 2011, versus a net loss of $25,869,000 (including a non-cash adjustment for increases in valuation of
warrants of $21,347,000) for fiscal year ended September 30, 2010.

       Revenue for the fiscal year ended September 30, 2011 was approximately $4,821,000, which compares to zero revenue for the fiscal
year ended September 30, 2010. The revenue is from the collaboration with BARDA announced on February 11, 2011. Since being awarded
the BARDA Contract, we generate contract revenue from a cost-plus fee arrangement. Revenues on reimbursable contracts are recognized as
costs are incurred, generally based on allowable costs incurred during the period, plus any recognizable earned fee. We consider fixed fees
under cost-plus fee contracts to be earned in proportion to the allowable costs incurred in performance of the contract.

      Research and Development

       Research and development expenses increased by about $3,365,000, or 199%, to approximately $5,055,000 for the fiscal year ended
September 30, 2011 from approximately $1,690,000 for the fiscal year ended September 30, 2010. R&D expenses were higher during the fiscal
year ended September 30, 2011 versus September 30, 2010 due to work related to the BARDA Contract. For the fiscal year ended
September 30, 2011, consultant expenses increased by about $264,000 due to costs associated with the aforementioned consultant. Preclinical
fees increased about $1,907,000 over the comparable period in 2010 due to increased animal studies to support our ARS development program.
The increase also reflected the initiation of production of a compound for oncology studies anticipated that began in fiscal year 2011, for which
manufacturing expenses increased about $1,118,000.

      R&D expenses for our antioxidant program have totaled approximately $42,255,000 from inception through September 30, 2011.
Because of the uncertainty of our research and development and clinical studies, we are unable to predict the total level of spending on the
program or the program completion date. However, we expect R&D expenses during fiscal year 2012 will be higher than fiscal 2011 since we
have been awarded the BARDA Contract. We anticipate that much of the increase in R&D spending should be reimbursed under that contract.

      General and Administrative

       General and administrative G&A expenses include corporate costs required to support our company, our employees and consultants and
our stockholders. These costs include personnel and outside costs in the areas of legal, human resources, investor relations and finance.
Additionally, we include in general and administrative expenses such costs as rent, repair and maintenance of equipment, depreciation, utilities,
information technology and procurement costs that we need to support the corporate functions listed above.

      G&A expenses increased approximately $1,714,000, or 88%, to approximately $3,668,000 for the fiscal year ended September 30, 2011
from about $1,954,000 for the fiscal year ended September 30, 2010. Salaries and wages increased by about $646,000 due to the addition of a
Chief Financial Officer, a Vice President of Manufacturing, a Director of Quality Assurance and Quality Control, and Corporate Controller.
Consulting stock expense increased by about $422,000 as a result of the hiring of the aforementioned staff and also due to decreased stock
compensation activity in the prior comparable period. Investor relations expenses increased by $118,000, due to increased IR-related activities
performed by outside consultants. Legal fees increased by $143,000 as a result of higher reliance on our outside legal counsel for review and
compliance related to SEC filings during the current quarter, as well as the review of the BARDA Contract and related contracts.

      Other Income or Expense

       We incurred interest expense of approximately $21,000 for the fiscal year ended September 30, 2011 compared to interest expense of
about $878,000 for the fiscal year ended September 30, 2010. The decrease in interest expense in fiscal year 2011 reflects about $21,000
incurred by the second quarter of fiscal year 2011, due to conversion of the Elan note payable compared to the conversion of the Senior
Convertible Notes during the prior comparable period.


                                                                       34
       As previously disclosed, certain of our warrants to purchase common stock were deemed to be a liability upon adoption of a new
accounting pronouncement on October 1, 2009. Subsequent changes to the fair market value resulted in an offsetting gain in the statements of
operations of approximately $3,887,000 for the fiscal year ended September 30, 2011, as compared to approximately $21,347,000 for the fiscal
year ended September 30, 2010. The warrant liability and revaluations have not and will not have any impact on our working capital, liquidity
or business operations.

Fiscal Year Ended September 30, 2010 Compared to Fiscal Year Ended September 30, 2009

      We had a net loss of $25,869,000 (including a non-cash gain for decreases in valuation of warrants of $21,347,000) for the fiscal year
ended September 30, 2010, versus a net loss of $2,296,000 for the fiscal year ended September 30, 2009.

      We did not generate any revenue during fiscal 2010 or fiscal 2009.

      Research and Development

        Research and development expenses increased by about $979,000, or 138%, to approximately $1,690,000 for the fiscal year ended
September 30, 2010 from approximately $711,000 for the fiscal year ended September 30, 2009. R&D expenses were higher during the fiscal
year ended September 30, 2010 versus September 30, 2009 due to an increase in research activities to support our lung acute radiation
syndrome (“ARS”) development program and the retention of a consultant to assist in the writing of proposals for government funding. For the
fiscal year ended September 30, 2010, consultant expenses increased by about $207,000 due to costs associated with the aforementioned
consultant. Preclinical fees increased about $692,000 over the comparable period in 2009 due to increased animal studies to support our ARS
development program. The increase also reflected the initiation of production of a compound for oncology studies that began in fiscal year
2011, for which manufacturing expenses were about $110,000.

      General and Administrative

       G&A expenses increased approximately $662,000, or 51%, to approximately $1,954,000 for the fiscal year ended September 30, 2010
from about $1,292,000 for the fiscal year ended September 30, 2009. Salaries and wages increased by about $138,000 due to the hiring of a
new employee during the first quarter of fiscal 2010. Consulting stock expense increased by about $247,000 as a result of a higher level of
grant activity to employees, consultants and directors. Investor relations expenses increased by $133,000, due to increased IR-related activities
performed by outside consultants. Legal fees increased by $126,000 as result of higher reliance on our outside legal counsel for review and
compliance related to SEC filings.

      Other Income or Expense

       We incurred interest expense of approximately $878,000 for the fiscal year ended September 30, 2010 compared to interest expense of
about $441,000 for the fiscal year ended September 30, 2009. The increase in interest expense in fiscal year 2010 reflects about $437,000
incurred in the first quarter of fiscal year 2010, mostly due to charges as a result of the conversion of the Notes on October 6, 2009 as part of
our October 2009 Financing. In the second, third and fourth quarters of 2010, interest expense dropped significantly mostly due to the
conversion of the Notes into equity.

       As previously disclosed, certain of our warrants to purchase common stock were deemed to be a liability upon adoption of a new
accounting pronouncement on October 1, 2009. Subsequent changes to the fair market value resulted in an offsetting charge in the statements
of operations of approximately $21,347,000 for the fiscal year ended September 30, 2010. The warrant liability and revaluations have not and
will not have any impact on our working capital, liquidity or business operations.

Liquidity and Capital Resources

       We had cash and cash equivalents of $390,000 on March 31, 2012, and $518,000 on September 30, 2011. The decrease in cash was
primarily due to cash used in operations. We had accounts receivable of $2,479,000 on March 31, 2012, and $1,677,000 on September 30,
2011. The increase was primarily due to the timing of the work under the BARDA Contract. We had accounts payable of $3,376,000 on March
31, 2012, and $2,144,000 on September 30, 2011. The increase was primarily due to the timing of the work under the BARDA Contract and
operations.

       We had net income of $5,740,000 (including a non-cash adjustment for decreases in valuation of warrants of $7,012,000) for the six
months ended March 31, 2012. We had cash outflows from operations of $513,000. We expect to incur additional losses and negative cash
flow from operations during the remainder of fiscal year 2012 and potentially for several more years.


                                                                        35
       On February 11, 2011, we were awarded the BARDA Contract to fund the development of AEOL 10150 as a medical countermeasure
for Lung-ARS from its current status to FDA approval in response to Special Instructions Amendment 4 to a Broad Agency Announcement
(BAA-BARDA-09-34) for advanced research and development of medical countermeasures for chemical, biological, radiological and nuclear
threats. The contract value could be up to $118.4 million depending on options exercised by BARDA and the requirements for approval by the
FDA. Under the BARDA Contract, substantially all of the costs of the development of AEOL 10150 as a medical countermeasure for
pulmonary injuries resulting from an acute exposure to radiation from a radiological/nuclear accident or attack, particularly injuries associated
with ARS or Delayed Effects of Acute Radiation Exposure would be paid for by the U.S. government through BARDA funding. We
recognized $2,231,000 in revenue during the quarter ended March 31, 2012 related to the BARDA Contract. The BARDA Contract include
provisions to cover some, but not all, general corporate overhead as well as a small provision for profit. The net impact of the contract on the
Company’s liquidity is that its projected cash burn has been reduced. Certain costs, typically those of being a public company, like legal costs
associated with being a public company, IR/PR costs and patent-related costs, are not included in overhead reimbursement in the BARDA
Contract.

      We do not have any revenues from product sales and, therefore, we rely on investors, grants, collaborations and licensing of our
compounds to finance our operations. We generate limited revenue from reimbursable, cost-plus R&D contracts and grants. Revenues on
reimbursable contracts are recognized as costs are incurred, generally based on allowable costs incurred during the period, plus any
recognizable earned fee. We consider fixed fees under cost-plus fee contracts to be earned in proportion to the allowable costs incurred in
performance of the contract.

        Since the terms of the BARDA Contract include provisions to cover some general corporate overhead as well as a small provision for
profit, the result on our liquidity is that our projected cash burn has been reduced. In order to fund on-going operating cash requirements or to
accelerate or expand our oncology and other programs we may need to raise significant additional funds.

       We have incurred significant losses from operations to date. Our ongoing future cash requirements will depend on numerous factors,
particularly the progress of our catalytic antioxidant program, potential government procurements for the national stockpile, clinical trials
and/or ability to negotiate and complete collaborative agreements or out-licensing arrangements. In addition, we might sell additional shares of
our stock and/or debt and explore other strategic and financial alternatives, including a merger or joint venture with another company, the sale
of stock and/or debt, the establishment of new collaborations for current research programs, that include initial cash payments and ongoing
research support and the out-licensing of our compounds for development by a third party.

        There are significant uncertainties as to our ability to access potential sources of capital. We may not be able to enter into any
collaboration on terms acceptable to us, or at all, due to conditions in the pharmaceutical industry or in the economy in general or based on the
prospects of our catalytic antioxidant program. Even if we are successful in obtaining collaboration for our antioxidant program, we may have
to relinquish rights to technologies, product candidates or markets that we might otherwise develop ourselves. These same risks apply to any
attempt to out-license our compounds.

        Similarly, due to market conditions, the illiquid nature of our stock and other possible limitations on equity offerings, we may not be
able to sell additional securities or raise other funds on terms acceptable to us, if at all. Any additional equity financing, if available, would
likely result in substantial dilution to existing stockholders.

      Our forecast of the period of time through which our financial resources will be adequate to support our operations is forward-looking
information, and actual results could vary.

Off-Balance Sheet Arrangements

       We do not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial
condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.


Relationship with Goodnow Capital, LLC and Xmark Opportunity Partners, LLC


                                                                          36
     In July 2003, we initiated a series of transactions that led to our corporate reorganization and recapitalization. We obtained an aggregate of
$8,000,000 in secured bridge financing in the form of convertible promissory notes we issued to Goodnow Capital, LLC (“Goodnow”). A
portion of this financing allowed us to pay our past due payables and become current. We used the remainder for our operations, including a
toxicology study for our catalytic antioxidant compounds under development as a treatment for ALS.

     We completed our corporate reorganization on November 20, 2003. The reorganization involved the merger of our former parent company
into one of our wholly owned subsidiaries. Subsequent to our 2003 reorganization, we completed a number of equity and debt financings, the
majority of which included affiliated fund of Xmark as investors. As of September 30, 2011, Xmark, through its management of Goodnow and
the Xmark Funds, and through the Xmark Voting Trust and options held by David Cavalier, an affiliate of Xmark and the Chairperson of our
Board of Directors, had voting power over 63% of our outstanding common stock and had beneficial ownership, calculated based on SEC
requirements, of approximately 73% of our common stock. As a result of this significant ownership, Xmark and its affiliates is able to control
future actions voted on by our stockholders.

     In addition, under the terms of the warrants to purchase up to 61,822,749 shares of our common stock issued to Xmark on October 6, 2009
as well as subsequent warrant issuances on July 30, 2010, August 11, 2010 and December 28, 2010 (collectively, the “Xmark Warrants”), if we
were to pay a dividend on our common stock the exercise price of the Xmark Warrants would be reset from $0.28 per share or $0.50 per share,
as applicable, to $0.01 per share and the warrant holders would also receive any such dividend paid. The Xmark Warrants also contain a
provision that provides for the reduction of the exercise price to $0.01 upon a change of control and anti-dilution provisions in the event of a
stock dividend or split, dividend payment or other issuance, reorganization, recapitalization or similar event. In addition, the Xmark Warrants,
among other restrictions, prohibit the sale of our company to an entity other than one that is publicly traded.

Critical Accounting Policies and Estimates

      Our consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States
of America, which require us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses and
related disclosure of contingent assets and liabilities. We evaluate our estimates, judgments and the policies underlying these estimates on a
periodic basis as the situation changes, and regularly discuss financial events, policies, and issues with our independent registered public
accounting firm and members of our audit committee. We routinely evaluate our estimates and policies regarding revenue recognition; clinical
trial, preclinical, manufacturing and patent related liabilities; license obligations; inventory; intangible assets; share-based payments; and
deferred tax assets.

     We generally enter into contractual agreements with third-party vendors to provide clinical, preclinical and manufacturing services in the
ordinary course of business. Many of these contracts are subject to milestone-based invoicing and the contract could extend over several years.
We record liabilities under these contractual commitments when we determine an obligation has been incurred, regardless of the timing of the
invoice. Patent-related liabilities are recorded based upon various assumptions or events that we believe are the most reasonable to each
individual circumstance, as well as based upon historical experience. License milestone liabilities and the related expense are recorded when
the milestone criterion achievement is probable. We have not recognized any assets for inventory, intangible items or deferred taxes as we have
yet to receive regulatory approval for any of our compounds. Any potential asset that could be recorded in regards to any of these items is fully
reserved. In all cases, actual results may differ from our estimates under different assumptions or conditions.

      Warrant Liability

     On October 1, 2009, the Company adopted new accounting guidance originally referred to EITF 07-5, recently codified by FASB as ASC
Topic 815. The guidance revised previously existing guidance for determining whether an Instrument (or Embedded Feature) is indexed to an
entity’s own stock. Equity-linked instruments (or embedded features) that otherwise meet the definition of a derivative are not accounted for as
derivatives if certain criteria are met, one of which is that the instrument (or embedded feature) must be indexed to the entity’s own stock. The
Company applied the new guidance to outstanding instruments as of October 1, 2009. The fair value of the warrants affected by the new
guidance at the dates of issuance totaled $8,282,000 and was initially recorded as a component of additional paid-in capital. Upon adoption of
the new guidance, the Company recorded a decrease to the opening balance of additional-paid-in capital of $8,142,000 and recorded a decrease
to accumulated deficit totaling $4,353,000, representing the decrease in the fair value of the warrants from the date of issuance to October 1,
2009. The fair value of the warrants at October 1, 2009 of $3,789,000 was classified as a liability in the balance sheet as of that date.


                                                                        37
       Increases or decreases in fair value of the warrants are included as a component of other income (expenses) in the accompanying
statement of operations for the respective period. As of September 30, 2011, the liability for warrants decreased to approximately $23,405,000,
resulting in an additional gain to the statements of operations for the fiscal year ended September 30, 2011 of approximately $3,887,000. The
warrant liability and revaluations have not and will not have any impact on the Company’s working capital, liquidity or business operations.

      Revenue Recognition

       We do not currently generate revenue from product sales, but do generate revenue from the BARDA Contract. We recognize revenue
from the BARDA Contract in accordance with the authoritative guidance for revenue recognition. Revenue is recognized when all of the
following criteria are met: (i) persuasive evidence of an arrangement exists, (ii) delivery (or passage of title) has occurred or services have been
rendered, (iii) the seller’s price to the buyer is fixed or determinable, and (iv) collectability is reasonably assured. We also comply with the
authoritative guidance for revenue recognition regarding arrangements with multiple deliverables.

       The BARDA Contract is classified as a “cost-plus-fixed-fee” contract. We recognize government contract revenue in accordance with
the authoritative guidance for revenue recognition, including the authoritative guidance specific to federal government contracts. Reimbursable
costs under the BARDA Contract primarily include direct labor, subcontract costs, materials, equipment, travel and indirect costs. In addition,
we receive a fixed fee under the BARDA Contract, which is unconditionally earned as allowable costs are incurred and is not contingent on
success factors. Reimbursable costs under this BARDA Contract, including the fixed fee, are recognized as revenue in the period the
reimbursable costs are incurred and become billable.



                                                                        38
                                                                  BUSINESS

General

    Overview

     Aeolus Pharmaceuticals, Inc. (“we,” “us” or the “Company”) is a Southern California-based biopharmaceutical company leveraging
significant government investment to develop a platform of novel compounds in oncology and biodefense. The platform consists of over 200
compounds licensed from Duke University (“Duke”) and National Jewish Health (“NJH”).

     Our lead compound, AEOL 10150, is being developed as a medical countermeasure (“MCM”) against the pulmonary sub-syndrome of
acute radiation syndrome (“Pulmonary Acute Radiation Syndrome” or “Lung-ARS”) as well as the gastrointestinal sub-syndrome of acute
radiation syndrome (“GI-ARS”). Both syndromes are caused by acute exposure to high levels of radiation due to a radiological or nuclear
event. It is also being developed for use as a MCM for exposure to chemical vesicants such as chlorine gas, phosgene gas, sulfur mustard gas
and nerve agents. AEOL 10150 has already demonstrated safety and efficacy in animal studies in each of these potential indications. AEOL
10150 has previously been tested in two Phase I clinical trials in humans with no serious adverse events reported. A Phase I study in healthy
normal volunteers is expected to be completed in 2012. A Phase II study in oncology, where AEOL 10150 will be used in combination with
radiation and chemotherapy, is planned for 2013.

    Strategy

   Our strategy is to use non-dilutive capital wherever possible to develop our exciting platform of broad-spectrum, catalytic antioxidant
compounds in important unmet medical indications of clinical and national strategic importance.

     We are currently executing this strategy with our lead compound, AEOL 10150, where we are leveraging a substantial (up to $118.4
million) government investment in the development of AEOL 10150 as a MCM for Lung-ARS to develop the compound for use in
combination with radiation and chemotherapy for cancer.

    To date, we, and/or our research collaborators, have been awarded more than $150 million in non-dilutive funding for three of our leading
compounds, AEOL 10150, AEOL 11206 and AEOL 10171 (also known as Hexyl).
Each of these three metalloporphyrins contains manganese and may be referred to as “manganese porphyrins” or “manganoporphyrins”. This
non-dilutive funding includes grants and contracts from U.S. government agencies, such as the Biomedical Advanced Research and
Development Authority (“BARDA”), a division of the Department of Health and Human Services (“HHS”), The National Institutes of Health
(“NIH”), the National Institute of Allergy and Infectious Diseases (“NIH-NIAID”) and the National Institutes of Health’s Countermeasures
Against Chemical Threats (“NIH-CounterACT”). Additionally, research is currently being conducted on several other compounds, including
AEOL 11207 and similar compounds, which is funded by private foundations, such as the Michael J. Fox Foundation and Citizens United for
Research in Epilepsy (“CURE.”).

     The expected benefit of this strategy is twofold. First, a significant portion of the research to be completed under the government funding
mechanisms, particularly the contract with BARDA is applicable to our AEOL 10150 development program for radiation therapy and
oncology. In addition to funding the development of the compound for the target indication of Lung-ARS, the contract with BARDA benefits
our oncology development program through data generated in areas like safety, toxicology, pharmacokinetics and Chemistry, Manufacturing
and Controls (“CMC”). Second, the purpose of the BARDA development contract is to fund AEOL 10150 so that procurements can be made
for the national stockpile. Procurements may be made if either the drug meets the requirements for approval by the U.S. Food and Drug
Administration (the “FDA”) under the “Animal Rule” or under an Emergency Use Authorization (“EUA”). Most of BARDA’s procurements
to date have been under an EUA. We expect to file an EUA for AEOL 10150 as a MCM for Lung-ARS as early as mid-2013.

     Procurements could generate significant cash and profit that could be re-invested to further develop AEOL 10150 for radiation oncology
indications (and other compounds for additional indications). The amount of any potential procurement is undisclosed by BARDA at this time
and is unknown to us. Based on publicly available information, as well as other procurements made by the agency under EUAs, we believe the
agency may purchase sufficient courses of therapy to treat a minimum of several hundred thousand people. This would provide sufficient
funding to complete numerous clinical studies, including potentially large Phase III programs in radiation oncology. This funding would allow
us to fund these studies without having to partner the compounds or to raise as much money through equity offerings, which would lead to
greater value for our stockholders.


                                                                       39
      Business Overview

    We are developing a new class of broad-spectrum, catalytic antioxidant compounds based on technology discovered at Duke University
and National Jewish Health, developed by Drs. Irwin Fridovich, Brian Day and others. Dr. Fridovich discovered Superoxide Dismutase
(“SOD”), which is a central enzyme in the human body for the detoxification of harmful oxygen free radicals formed by the metabolism of
organisms. One source of increased production of free radicals is exposure to ionizing radiation.

     These compounds, known as metalloporphyrins, scavenge ROS at the cellular level, mimicking the effect of the body’s own natural
antioxidant enzyme, SOD. While the benefits of antioxidants in reducing oxidative stress are well-known, research with our compounds
indicates that metalloporphyrins can be used to affect signaling via ROS at the cellular level. In addition, there is evidence that high-levels of
ROS can affect gene expression and this may be modulated through the use of metalloporphyrins. We believe this could have a profound
beneficial impact on people who have been exposed, or are about to be exposed, to high-doses of radiation, whether from cancer therapy or a
nuclear event.

     Our lead compound, AEOL 10150, is a metalloporphyrin specifically designed to neutralize reactive oxygen and nitrogen species. The
neutralization of these species reduces oxidative stress, inflammation, and subsequent tissue damage-signaling cascades resulting from
radiation or chemical exposure. We are developing AEOL 10150 in both oncology and as a biodefense medical countermeasure.

     AEOL 10150 is currently being developed as a MCM for GI-ARS and Lung-ARS, both of which are caused by exposure to high levels of
radiation due to a radiological or nuclear event. On February 11, 2011, we signed an agreement with BARDA for the development of AEOL
10150 as a MCM against Lung-ARS (the “BARDA Contract”). Pursuant to the BARDA Contract we will receive approximately $10.4 million
in the first year base period. We may receive up to an additional $108 million in options exercisable over four years following the first year
base period. If all of the options are exercised by BARDA, the total value of the contract is approximately $118.4 million. Also, pursuant to the
BARDA Contract, we expect to file an EUA as early as mid-2013. Once the EUA is filed, it would be possible for BARDA to begin procuring
the drug for the strategic national stockpile. Procurements from BARDA may result in significant revenues for our company.

    Until February 2011, the Lung-ARS program was principally funded by us and the work was performed at Duke University and the
University of Maryland. Since February 11, 2011, substantially all of the costs for the Lung-ARS program have been funded by the BARDA
Contract. To date, the GI-ARS development program has been funded by the NIH-NIAID through programs at the University of Maryland and
Epistem, Ltd., and the chlorine and mustard gas programs have been funded by NIH-CounterACT through programs at National Jewish Health
and the University of Colorado.

     We are leveraging the significant investment made by U.S. government agencies to develop this promising compound for use in oncology
indications, where it would be used in combination with radiation and chemotherapy, and is currently in development for use as both a
therapeutic and prophylactic drug. Studies have already demonstrated that AEOL 10150 does not interfere with the benefit of radiation therapy
in prostate and lung cancer preclinical studies and has its own anti-tumor activity as well.

     Upon the successful completion of the Phase I study and approval of a protocol by the FDA and the appropriate Institutional Review
Boards (“IRBs”), we expect to begin a Phase II study in non-small cell lung cancer (“NSCLC”) patients. Radiation therapy is a key therapy in
NSCLC. It is the treatment of choice for patients with unresectable Stage I-II disease, and is recommended, in combination with chemotherapy,
for patients with unresectable stage IIIB disease. (Pipeline Insight: Cancer Overview – Lung, Brain, Head and Neck, Thyroid; Datamonitor
2008, 37.). Radiation therapy lowers the level of the lung’s surfactant, a substance that helps the lungs expand. This can result in a dry cough
or shortness of breath. Radiation pneumonitis is an inflammatory response of the lungs to radiation, which can occur one to six months
following the completion of radiation therapy. Pulmonary fibrosis, which refers to the formation of scar tissue in the lungs, can also occur from
radiation therapy for lung cancer.

     NIAID’s Radiation/Nuclear Medical Countermeasures development program is currently testing AEOL 10150 as a countermeasure for
GI-ARS caused by exposure to high levels of radiation due to a radiological or nuclear event. Similarly, the NIH-CounterACT program has
tested, and continues to test, AEOL 10150 as a medical countermeasure for exposure to chemical vesicants such as chlorine gas, phosgene gas,
mustard gas and nerve agents. In September 2010, BARDA invited us to submit a full proposal in response to our white paper for the
development of AEOL 10150 as an MCM to chlorine gas exposure. BARDA also informed us that it had not accepted the white paper for
sulfur mustard gas. The proposal sought funding to take the compound from its current state to FDA approval over a three year period. We
submitted our full proposal to BARDA in December 2010. On June 28, 2011, BARDA informed us that it would not be entering into
negotiation with us for the development of the chlorine indication at this time, but invited us to resubmit our proposal after completion of some
of the safety and efficacy studies in our current Lung-ARS program funded by BARDA. BARDA indicated in its response that there was some
overlap in the development program proposed and the current BARDA Contract, and that it was already funding the radiation indication, which
is a very similar program. In October 2011, we announced that National Jewish Health was awarded a $12.5 million contract from
NIH-CounterACT to continue the development of AEOL 10150 as a MCM against chlorine gas and sulfur mustard gas exposure. Also
included in the grant is support for research in looking at tissue plasminogen activator (TPA) and Silabilin as MCMs against sulfur mustard gas
exposure. The ultimate objective of the sulfur mustard and chlorine gas work at National Jewish Health will be to complete all work necessary
to initiate pivotal efficacy studies for both indications. This would include: running efficacy studies in the rat model for higher doses of sulfur
mustard and chlorine gas; establishing endpoints, optimal dosing and duration of treatment for pivotal efficacy studies; and characterizing the
natural history from sulfur mustard and chlorine gas damage. NIH-CounterACT has also awarded a contract, worth approximately $735,000, to
the University of Colorado to develop AEOL 10150 as a MCM against nerve agents.


                                                                   40
     AEOL 10150 has already performed well in animal safety studies, been well-tolerated in two human clinical safety studies, demonstrated
efficacy in two species in acute radiation syndrome (“ARS”) studies and demonstrated statistically significant survival efficacy in an acute
radiation-induced lung injury model. AEOL 10150 has also demonstrated efficacy in validated animal models for GI-ARS, chlorine gas
exposure, and sulfur mustard gas exposure. Efficacy has been demonstrated in Lung-ARS in both mouse and non-human primate studies
(“NHP”), with AEOL 10150 treated groups showing significantly reduced weight loss, inflammation, oxidative stress, lung damage, and most
importantly, mortality in the mouse study. Therapeutic efficacy was demonstrated when delivered after exposure to radiation (24 hours after
exposure for mice in the GI-ARS study and NHPs in the Lung-ARS studies, and two hours after exposure for mice in the Lung-ARS studies).

     We have an active Investigational New Drug Application (“IND”) on file with the FDA for AEOL 10150 as a potential treatment for
amyotrophic lateral sclerosis (“ALS”). We expect to file an IND for Lung-ARS with the Division of Medical Imaging Products in 2012. Also
in 2012, we plan to file an IND for cancer with the oncology division of the FDA, and may also file INDs for the GI-ARS and chlorine gas
indications. We have already completed two Phase I safety studies in 50 humans demonstrating that the drug is safe and well tolerated. CMC
work has been completed, pilot lots have been prepared and production is beginning to scale up under the BARDA Contract. Currently, we
have no plans to conduct further clinical trials in ALS.

    We have two programs underway for the development of our second drug candidate, AEOL 11207, for the treatment of epilepsy and
Parkinson’s disease. These programs are being funded, in part, by private foundations, including the Michael J. Fox Foundation, CURE and
government grants.

    Our third drug candidate, AEOL 10171 (also known as Hexyl), is the subject of a $20 million research grant from NIH-NIAID, for
development as a potential MCM for ARS.

Aeolus’ Catalytic Antioxidant Program

         The findings of research on natural antioxidant enzymes and antioxidant scavengers support the concept of antioxidants as a broad
new class of therapeutic drugs, if certain limitations noted below could be overcome. We established our research and development program to
explore and exploit the therapeutic potential of small molecule catalytic antioxidants. We have achieved our initial research objectives and
begun to extend our preclinical accomplishments into non-clinical studies, clinical trials and drug development programs.

        Our catalytic antioxidant program is designed to:
  ● Retain the catalytic mechanism and high antioxidant efficiency of the natural enzymes, and

  ● Create and develop stable and small molecule antioxidants without the limitations of SOD so that they:

         o Have broader antioxidant activity,

               o Have better tissue penetration,



                                                                     41
               o Have a longer life in the body, and

               o Are not proteins, which are more difficult and expensive to manufacture.

          We created a class of small molecules that consume reactive oxygen and nitrogen species catalytically; that is, these molecules are not
themselves consumed in the reaction. Our class of compounds is a group of manganoporphyrins (an anti-oxidant containing manganese) that
retain the benefits of antioxidant enzymes, are active in animal models of disease and, unlike the body’s own enzymes, have properties that
make them suitable drug development candidates.

          Our most advanced compound, AEOL 10150 (Figure 1), is a small molecule, broad-based, catalytic antioxidant that has shown the
ability to scavenge a broad range of reactive oxygen species, or free radicals. As a catalytic antioxidant, AEOL 10150 mimics, and thereby
amplifies, the body’s natural enzymatic systems for eliminating these damaging compounds. Because oxygen- and nitrogen-derived reactive
species are believed to have an important role in the pathogenesis of many diseases, we believe that our catalytic antioxidants and AEOL 10150
may have a broad range of potential therapeutic uses.

                                                                    Figure 1




         AEOL 10150 has shown efficacy in a variety of animal models as a protectant against radiation injury, sulfur mustard gas exposure,
ALS, stroke, pulmonary diseases, and diabetes. We filed an IND for AEOL 10150 in April 2004, under which clinical trials were conducted as
more fully described below under the heading “AEOL 10150 in Amyotrophic Lateral Sclerosis.” In 2012, we plan to file an IND for Lung-ARS
with the medical imaging products division of the FDA and an additional IND with the oncology division of the FDA. For a more detailed
description of antioxidants see the section below under the heading “Background on Antioxidants.”

AEOL 10150 Medical Countermeasure Development Program

AEOL 10150 has performed well in animal safety studies, was well-tolerated in two human clinical trials, and has demonstrated statistically
significant survival efficacy in an acute radiation-induced lung injury model. AEOL 10150 has also demonstrated efficacy in validated animal
models for GI-ARS, chlorine gas exposure, sulfur mustard gas exposure and nerve agent exposure. Based on this research, Aeolus and it’s
research partners have been awarded in excess of $139 million for the development of AEOL 10150 as a dual-use, broad spectrum medical
countermeasure. The table below details the indications currently under development and the sources of funding from the U.S. Government.

AEOL 10150 as a potential medical countermeasure against the effects of Pulmonary Acute Radiation Syndrome

      Overview

    During recent years, the threat of nuclear attack on U.S. soil has increased. The lack of efficient post-exposure treatments for victims
experiencing acute radiation toxicity presents a serious problem should an attack with a radiological device occur.

     Immediately after exposure, the most critical components of acute radiation syndrome are the hematopoietic (bone marrow) and
early-onset GI-ARS because symptoms begin very quickly and can be lethal. However, depending on the level and location of radiation
exposure, much of the lethality of both hematopoietic and early-onset gastrointestinal syndromes are potentially avoidable with proper
treatment, including supportive care (fluids and antibiotics) and Neupogen (granulocyte colony-stimulating factor, or G-CSF), leaving
complications to later responding tissues, like the lungs, subsequently becoming a major problem, and in some cases, becoming a cause of
death.

    In situations of accidental exposure, it was initially assumed that a whole-body dose exceeding 10 Gray (“Gy”) was inevitably fatal.
However, experience with nuclear accident victims suggests that when patients survive gastrointestinal and bone marrow syndromes,
respiratory failure becomes a major cause of death. This effect is known as a delayed effect of acute radiation exposure (“DEARE”).

     Research has shown that damage associated with the exposure to upper half body irradiation or total body irradiation is an acute, but
delayed, onset of radiation pneumonitis (inflammation of lung tissue) followed by lung fibrosis (scarring caused by inflammation).The
incidence of radiation pneumonitis rises very steeply at relatively low radiation doses. A nuclear incident is likely to result in a wide,
inhomogeneous distribution of radiation doses to the body that allows hematological recovery. But a higher exposure to the thorax leaves open
the risk of serious pulmonary complications.

     For the government, interested in saving as many citizens’ lives as possible, it makes little sense to provide care to allow people to survive
the short-term effects of radiation exposure following an event, to merely have them die several weeks or months later due to the delayed
effects of radiation exposure.

     AEOL 10150 has already performed well in animal safety studies, been well-tolerated in two human clinical trials, demonstrated efficacy
in two species in ARS studies and demonstrated statistically significant survival efficacy in an acute radiation-induced lung injury model.
AEOL 10150 has also demonstrated efficacy in validated animal models for GI-ARS, chlorine gas exposure, and sulfur mustard gas exposure.
Efficacy has been demonstrated in both Lung-ARS and DEARE in both rodent and NHP studies, with AEOL 10150 treated groups showing
significantly reduced weight loss, inflammation, oxidative stress, lung damage, and most important, mortality. Therapeutic efficacy was
demonstrated when delivered after exposure to radiation (24 hours after exposure for mice in the GI-ARS studies and NHPs in the Lung-ARS
studies, and two hours after exposure for mice in the Lung-ARS studies).We expect to look at longer post exposure periods in future studies.


                                                                        43
      Pre-clinical studies

    Clinical experience and experience with nuclear accident victims points out that one of the primary concerns associated with radiation
exposure is an acute, but delayed onset of radiation pneumonitis with an incidence that rises very steeply at relatively low radiation doses (to
90-percent occurrence at 11 Gy). To evaluate AEOL 10150’s ability to mitigate acute radiation-induced lung injury, mice were exposed to 15
Gy of upper half body irradiation (“UHBI”) and subsequently treated with AEOL 10150.

     In a study led by Zeljko Vujaskovic, M.D., Ph.D. at Duke University Medical Center, C57BL/6 female mice were randomized into six
groups. Each of the groups was paired to include irradiated and non-irradiated groups of animals that were untreated, treated with a low dose
(10 mg/kg) of AEOL 10150, or treated with a high dose of AEOL 10150 (20 mg/kg). Animals received treatments subcutaneously beginning 2
hours after irradiation (20 and 40 mg/kg initial loading dose, respectively) followed by a maintenance dose of half the initial dose three times
per week for 4 weeks. Survival, wet lung weights and body weights, histopathology, and immunohistochemistry were used to assess lung
damage. Results demonstrate that treatment with AEOL 10150 increased survival (Fig.6), maintained body weight (Fig.7), protected lung tissue
(Fig.8 and 9), and reduced oxidative stress (via DNA and protein oxidation analysis) compared with untreated irradiated animals.




Figure 2. Kaplan Meier survival curves for C57BL/6J mice after upper half body irradiation. The survival data displayed that there were
no deaths in the sham-irradiated animals and animals receiving drug alone. In contrast, 9/20 (45%) of the animals that received 15 Gy UHBI
died during the 6-week follow-up period. Treatment with low/high doses of AEOL 10150 markedly reduced radiation-induced mortality to only
10% (2/20).

     Data from a study in which AEOL 10150 was administered to 40 mice that had been exposed to radiation also show a statistically
significant increase in survival rates among mice that were treated with AEOL 10150 compared to controls. Additionally, mice receiving
AEOL 10150 experienced a reversal in weight loss seen in the untreated mice. The six month study, led by Zeljko Vujaskovic, M.D., Ph.D. at
Duke University Medical Center, was designed to test the efficacy of AEOL 10150 as a treatment for damage to the lungs due to exposure to
radiation. At 45 days, all of the animals in the untreated group had either died or been sacrificed based on animal care rules. The remaining
animals that received AEOL 10150 did not need to be sacrificed based on animal care rules, but a majority were sacrificed in order to increase
the numbers that could be compared to the untreated animals sacrificed at 45 days, since there would be no untreated animals for comparison at
the end of six months. In addition to the statistically significant (P< 0.05) survival advantage, statistically significant differences in body
weights and wet lung weights were seen over the first six weeks of the study. Untreated mice experienced a steady decline in body weight over
the six weeks, while treated animals experienced weight gain that was just slightly less than that seen in the controls (animals not receiving
radiation). AEOL 10150 also demonstrated statistically significant reductions in markers for oxidative stress and inflammation, which were
secondary endpoints for the study.

     A number of other preclinical studies by Zeljko Vujaskovic, MD, PhD; Mitchell Anscher, MD, et al at Duke University have demonstrated
the efficacy of AEOL 10150 in radioprotection of normal tissue. Chronic administration of AEOL 10150 by continuous, subcutaneous infusion
for 10 weeks has demonstrated a significant protective effect from radiation-induced lung injury in rats. Female Fisher 344 rats were randomly
divided into four different dose groups (0, 1, 10 and 30 mg/kg/day of AEOL 10150), receiving either short-term (one week) or long-term (ten
weeks) drug administration via osmotic pumps. Animals received single dose radiation therapy of 28 Gy to the right hemithorax. Breathing
rates, body weights, histopathology and immunohistochemistry were used to assess lung damage. For the long term administration, functional
determinants of lung damage 20 weeks post-radiation were significantly decreased by AEOL 10150. Lung histology at 20 weeks revealed a
significant decrease in structural damage and fibrosis. Immunohistochemistry demonstrated a significant reduction in macrophage
accumulation, collagen deposition and fibrosis, oxidative stress and hypoxia in animals receiving radiation therapy along with AEOL 10150.
Figure 6 below shows a semi-quantitative analyses of lung histology at 20 weeks which revealed a significant decrease in structural damage
and its severity in animals receiving 10 and 30 mg/kg/day after radiation in comparison to radiation therapy along with placebo group or
radiation therapy along with 1 mg/kg of AEOL 10150 (p = 0.01).

                                                                   Figure 6




Figure 6 above shows that AEOL 10150 treatment decreases the severity of damage and increases the percentage of lung tissue with no
damage from radiation therapy (Rabbani et al Int J Rad Oncol Biol Phys 67:573-80, 2007).

     Two additional studies examining the effect of subcutaneous injections of AEOL 10150 on radiation-induced lung injury in rats have been
completed. The compound was administered subcutaneously by a b.i.d. dosing regimen (i.e., 2.5 mg/kg or 5.0 mg/kg) on the first day of
radiation and daily for five consecutive weeks. Radiation was fractionated rather than single dose, with 40 Gy divided in five 8 Gy doses.
Preliminary immunohistologic analyses of the lung tissue from these two studies showed a dose dependent decrease in the inflammatory
response quantified by the number of activated macrophages or areas of cell damage. These in vivo studies employing subcutaneous
administration of AEOL 10150, either by continuous infusion via osmotic pump or BID injection, demonstrate that AEOL 10150 protects
healthy lung tissue from radiation injury delivered either in a single dose or by fractionated radiation therapy doses. AEOL 10150 mediates its
protective effect(s) by inhibiting a number of events in the inflammatory cascade induced by radiation damage.

     Additional in vivo studies have been performed that provide support for manganoporphyrin antioxidant protection of lung tissue from
radiation. Treatment with a related manganoporphyrin compound, AEOL 10113 significantly improved pulmonary function, decreased hi
stopathologic markers of lung fibrosis, decreased collagen (hydroxy proline) content, plasma levels of the profibrogenic cytokine, transforming
growth factor beta (TGF-β) and, as demonstrated by immunohistochemistry of lung tissue, collagen deposition and TGF-β.

     In 2011, we announced positive results from study of AEOL 10150 and Neupogen(R) as combination therapy for treatment of ARS. The
study was conducted by Christie Orschell, PhD of Indiana University. The primary endpoint of the study was to determine drug-drug
interactions between Neupogen® and AEOL 10150, as well as to monitor safety and tolerability of the two treatments given simultaneously.
Results of the study confirmed that AEOL 10150 does not interfere with the positive effects of Neupogen® on the hematopoietic, or bone
marrow, syndrome of Acute Radiation Syndrome (ARS), and the two products in combination were safe and well tolerated.

     The study entitled "Pilot Study to Test the Effects of Aeolus 10150 on Neupogen®-Induced ANC Recovery in Sub-Lethally Irradiated
C57Bl/6 Mice" was initiated at the request of Shigetaka Asano, MD of Waseda University and Arinobu Tojo, MD, PhD and Tokiko Nagamura,
MD at the Institute of Medical Science at the University of Tokyo to determine whether there would be any interference with the demonstrated
efficacy of Neupogen® as a medical countermeasure against the hematopoietic complications of radiation exposure. In previous treatment of
radiation accident victims at Tokai-mura, Dr. Asano and others were able to use Granulocyte Colony Stimulating Factor (G-CSF) and
supportive care to enable victims of 8 to 12 Gy exposure to survive the hematopoietic (heme) syndrome. Unfortunately, these patients later died
due to lung and multi-organ complications. As AEOL 10150 has shown efficacy against lung and GI complications in mice and in Lung-ARS
in non-human primates, it was important to test whether the two compounds can be used in tandem, if necessary.


                                                                      46
     The use of Neupogen® or other G-CSFs or Neulasta® or other Granulocyte-Macrophage Colony Stimulating Factor (GM-CSF) products
is recommended by the Radiation Emergency Assistance Center/Training Site (REAC/TS) at radiation exposures greater than 2 to 3 Gy to
mitigate damage to the hematopoietic system. REAC/TS is a response asset of the U.S. Department of Energy and provides treatment
capabilities and consultation assistance nationally and internationally. In animal studies G-CSF's have been shown to be effective in increasing
survival at levels up to 7.5 Gy due to their positive effects on the hematopoietic damage created by radiation exposure. This class of
compounds has not demonstrated an effect on the two other major sub-syndromes -- GI and Lung. AEOL 10150 has demonstrated efficacy in
treating the GI sub-syndrome in pilot studies conducted by NIH-NIAID, by protecting crypt cells and reducing diarrhea. More extensive studies
of the drug in treating the pulmonary effects of radiation at Duke University and the University of Maryland have shown improved survival and
enhanced lung function and improved histology at exposures up to 15 Gy in mice and 11.5 Gy in non-human primates. These exposure levels
caused death in 100 percent of untreated animals. Studies at Duke University have also shown a significant survival advantage for animals
treated with AEOL 10150 after 15 Gy upper half body irradiation, which causes lethal damage to both the GI tract and the lungs.

     AEOL 10150 has consistently shown a protective effect against the harmful effects in radiation, including when the drug is administered
up to 72 hours after exposure.

     During fiscal year 2010, we initiated another study in mice to determine the optimal length of treatment with AEOL 10150 when used as
an MCM to Lung-ARS. This study, led by Zeljko Vujaskovic, M.D., Ph.D. at Duke University, was designed to build on the previously
completed study that demonstrated the efficacy of AEOL 10150 as a treatment for damage to the lungs due to exposure to radiation (described
in detail above), and determine the most effective duration of delivery for treatment after exposure. The results from the study showed that
treatment for 4 to 10 weeks after exposure appears to be optimal. Under the BARDA Contract, additional studies will be performed to further
refine the timeline and analyze whether extending treatment beyond 10 weeks would be beneficial. Treatment for 4, 6 and 10 weeks showed the
greatest impact on body weight and lung damage as shown in figures 7 and 8 below.

                               Figure 7                                                               Figure 8




Non-clinical studies

     In 2010, we initiated a study to confirm the efficacy of AEOL 10150 as an MCM to nuclear and radiological exposure in non-human
primates. The study was designed to test the efficacy of AEOL 10150 as a treatment for Lung-ARS and to begin establishing an animal model
that can be validated and could be utilized by the FDA for approval of an MCM for Pulmonary Acute Radiation Syndrome under the “Animal
Rule”. The FDA “Animal Rule” enumerates criteria whereby the FDA can rely on animal efficacy data when “evidence is needed to
demonstrate efficacy of new drugs against lethal or permanently disabling toxic substances when efficacy studies in humans, ethically cannot
be conducted.” The criteria are discussed below.




                                                                      47
     Preliminary results from the study were reported during the fiscal year, showing that AEOL 10150 promotes survival in a non-human
primate model of Lung-ARS. The primary objective of the study was to determine if AEOL 10150 could mitigate radiation-induced lung injury
and enhance survival in rhesus macaques exposed to whole thorax lung irradiation (“WTLI”) and administered supportive care. Two cohorts of
NHPs were exposed to 11.5Gy LINAC-derived photon radiation in the WTLI protocol. The control cohort had n=6 and AEOL 10150-treated
cohort was n=7.This model showed 100% incidence of severe radiation-induced lung damage. AEOL 10150 was administered subcutaneously
at 5mg/kg beginning at day 1 post WTLI and continued as a single, daily injection for 28 consecutive days. The final results were presented at
the 14th International Congress of Radiation Research in Warsaw, Poland in September 2011. Key findings in the study include:

    1.   Exposure of the whole thorax to 11.5 Gy resulted in radiation-induced lung injury in all NHPs in the study and proved 100% fatal in
         the control animals, despite supportive care including dexamethasone. 11.5 Gy is, therefore, equal to or greater than the LD 100/180 dose
         for the WTLI model.

    2.   AEOL 10150, as administered in this pilot study (daily on d1-28 at 5mg/kg SC), demonstrated potential efficacy as a mitigator
         against fatal radiation-induced lung injury. Treatment with the drug resulted in 28.6% survival following exposure to a radiation dose
         that proved to be 100% fatal in the untreated control group.

    3.   Serial CT scans demonstrated less quantitative radiographic injury (pneumonitis, fibrosis, effusions) in the AEOL 10150 treated
         cohort, suggesting that the drug reduces the severity of the radiographically detectable lung injury.

    4.   Dexamethasone administration yielded a transient benefit on both clinical and radiographic evidence of pneumonitis. The AEOL
         10150 treated cohort required 1/3 less dexamethasone support due to reduced pulmonary injury in the AEOL 10150 treated group,
         resulting in less frequent clinical “triggers” (respiratory rate≥80) to treat with dexamethasone.

    5.   The results of this pilot study are encouraging and suggest that treatment with AEOL 10150 results in reduced clinical, radiographic
         and anatomic evidence of radiation-induced lung injury, which also results in improved survival. AEOL 10150 merits further study
         as a post-exposure MCM against radiation-induced lung injury.

     In rodents, non-human primates and humans, radiation of the lungs can cause reduced breathing capacity, pneumonitis, fibrosis, weight
loss and death and is characterized by oxidative stress, inflammation and elevated macrophage counts. AEOL 10150 has proven to be an
effective countermeasure to radiation exposure of the lungs in mice and rats in published studies such as Rabbani et al Int J Rad Oncol Biol
Phys 67:573-80, 2007, Rabbani et al Free Rad Res 41:1273-82, 2007 and Gridley et al Anticancer Res 27:3101-9, 2007.

Clinical studies

     We believe our two previous Phase I clinical studies can be utilized in any potential IND and NDA filing with the FDA for AEOL 10150
as an MCM for ARS. We do not have any clinical trials currently underway, but we are in the process of planning a safety study in up to 60
Healthy Normal Volunteers, which would be funded by the BARDA Contract. The Company will be meeting with the Medical Imaging
Products division of the FDA on June 27, 2012 to discuss this protocol and an IND filing for the indication of Pulmonary Effects of Acute
Radiation Injury. We expect to commence the phase 1 study in the fourth quarter of 2012.

 Future Development Plans

    Our objective is to develop AEOL 10150 as an MCM against Lung-ARS, via the FDA’s “Animal Rule”. This development pathway
requires demonstration of the key study efficacy parameter of AEOL 10150 treatment in two animal models relevant to the human radiation
response and its treatment, demonstration of safety in humans, demonstration of relevant dosing and administration in humans, and clear
identification of the mechanism of radiation-induced damage to the lung and its amelioration by the drug candidate.

    AEOL 10150 has several distinct advantages as an MCM, including the following:


                                                                        48
             ● Demonstrated survival increase in animal studies when administered 2 hours after exposure (P<0.05),
             ● Demonstrated reduction in lung fibrosis in animal studies up to 24 hours post exposure (P<0.05),
             ● Demonstrated histological improvement in lung tissue post-radiation exposure,
             ● Addresses an unmet medical need as an MCM to Lung-ARS,
             ● Established safety profile in both clinical and pre-clinical studies,
             ● Subcutaneous self-administration possible by exposed individuals during emergency,
             ● Rapid administration, allowing large numbers of patients to be treated quickly,
             ● Stable for up to 4½ years at 0–8°C and 1 year at room temperature,
             ● Requires no non-standard storage conditions (i.e., not photosensitive),
             ● Currently in development as an adjunct to radiation therapy; if approved will provide a pre-existing distribution and stockpile
                  resource at oncology centers in the event of a radiological emergency,
             ● Demonstrated potential as both a therapeutic and prophylactic,
             ● Demonstrated potential to address multiple sub-syndromes of ARS,
             ● Demonstrated potential to address sulfur mustard gas, phosgene gas,chlorine gas and nerve agent exposure, and
             ● Potential dual use as an adjunct treatment for cancer patients receiving radiation therapy.

    We believe that in order to file a NDA for ARS with the FDA, we will need to demonstrate efficacy in animal models and demonstrate
product safety which is based upon the FDA’s “Animal Rule”. We also plan on pursuing Fast Track submission status for this indication,
enabling rolling NDA submission process and a key step in achieving Priority Review, if accepted by the FDA. The FDA determines within 45
days of a company’s request, made once the complete NDA is submitted, whether a Priority or Standard Review designation will be assigned.

     The FDA’s “Animal Rule” enumerates criteria whereby the FDA can rely on animal efficacy data when evidence is needed to demonstrate
efficacy of new drugs against lethal or permanently disabling toxic substances when efficacy studies in humans cannot be ethically conducted.
The criteria are as follows:

             ● Knowledge of the mechanism of radiation-induced damage to the lung and its amelioration by the candidate drug.
             ● Pharmacokinetic and pharmacodynamic analysis to provide information on relevant dose and administration schedule.
             ● Direct correlation of key study parameters (e.g., survival or major morbidity) with the desired clinical benefit in humans.
             ● Collection of efficacy data in two species relevant to the human radiation response and its treatment unless otherwise
                  justified under GLP-compliant conditions.
             ● A Phase I safety trial using the same product and formulation as used in the pivotal trial(s) required.

Demonstrate Efficacy in Animal Models

     Our efficacy plan is designed to accomplish two key goals: the validation of two animal models for acute radiation-induced lung injury and
the generation of pivotal efficacy data in these species. The efficacy data produced in pivotal studies using these validated models will provide
the data required to demonstrate efficacy of AEOL 10150 at the dose and schedule proposed for licensure. A second criterion of the “Animal
Rule” is that the models must be reflective of “real world” conditions to which a human is likely to be exposed. The proposed models have
been designed to reflect these real world conditions. Initial studies have been conducted with whole thorax exposure models to irradiate the
total lung parenchym, and will be followed by studies with Total Body Irradiation with shielding of roughly 5 percent of bone marrow. This
study design mimics real world conditions in which it is anticipated that many of those exposed to radiation will benefit from some shielding
(e.g., from cars, buildings, etc.), which will protect some bone marrow and allow for survival without a bone marrow transplant. This shielding
approach has been used to develop both murine and NHP models for GI-ARS and in the NHP models for radiation-induced lung injury.

Demonstrate Product Safety

     For product approval under the “Animal Rule”, we will also demonstrate product safety using the same product and formulation used in
the animal efficacy trials and proposed for use in humans. Demonstration of safety includes preclinical demonstration of safety via the standard
pre-clinical studies and analyses methods and Phase I safety trials sufficient to demonstrate product safety in the target patient population. We
believe our safety studies completed as a therapy for ALS may be utilized to demonstrate safety for this indication. We also plan to conduct
two additional Phase I clinical safety studies, which are included in the BARDA Contract.


                                                                       49
Competition

   Currently there are no FDA-approved drugs for the treatment of Lung-ARS. We are also not aware of any other drug candidates that have
demonstrated the ability to protect the lungs from radiation given post exposure, which we believe is a critical aspect of the development of an
MCM against the effects of acute radiation syndrome.

     However, in general, we face significant competition for U.S. government funding for both development and procurements of an MCM for
biological, chemical and nuclear threats, diagnostic testing systems and other emergency preparedness countermeasures. The U.S. federal
government has currently allocated a significant amount of research funding to the development of countermeasures against the effects of
radiation exposure. As a result, there are many drug candidates under development as a possible countermeasure against the various effects and
sub-syndromes of radiation exposure.

Funding and Funding Options

     In October 2010, we were notified that we had been awarded the maximum amount of about $244,000, under the QTDP administered by
the IRS and the HHS in support of our development of AEOL 10150 as an MCM for Lung-ARS.

      On February 11, 2011, we signed an agreement with BARDA for the development of AEOL 10150 as a medical countermeasure against
the pulmonary sub-syndrome of acute radiation syndrome, pursuant to which we will receive approximately $10.4 million from BARDA in the
first year base period of performance and up to an additional $108 million in options exercisable over four years following the first year base
period of performance, if the options are exercised by BARDA, for a contract value of up to approximately $118.4 million. During fiscal year
2011, the Company received $4.8 million in funding under the BARDA Contract. During the first six months for fiscal year 2012, the
Company received $4.5 million in funding under the BARDA Contract.. On April 16, 2012, we announced that BARDA had exercised two
contract options worth approximately $9.1 million. The bulk of the options are for the period of performance beginning April 1, 2012 and
ending March 31, 2013.

    Since we have been awarded the BARDA Contract, substantially all of the costs associated with the research and development of AEOL
10150 as a MCM for Lung-ARS have been covered by the BARDA Contract, and we expect such costs to continue to be covered by the
BARDA Contract. The following are the key deliverables that will be reviewed and the status of these milestones and deliverables.

AEOL 10150 as a potential medical countermeasure against the effects of radiation on the gastro-intestinal tract

Overview

     GI-ARS is a massive, currently untreatable, problem following high-dose, potentially lethal radiation exposure. Agents that mitigate these
effects would reduce sickness and hopefully prevent fatalities. The intestinal epithelium, a single layer of cells lining the surface of the GI
lumen, is responsible for vital functions of nutrient absorption, maintaining fluid and electrolyte balance and protection of the body from
bacteria, bacterial toxins and non-absorbed materials. The functional integrity of the GI system is maintained via incessant production of
epithelial cells from specialized stem cells located in crypts at the base of the epithelium. High-dose, total-body irradiation can result in a lethal
GI syndrome that results in significant morbidity and mortality within days consequent to killing of the crypt stem cells and loss of the
protective and absorptive epithelial barrier. There are no FDA-approved drugs or biologics to treat GI-ARS.

Pre-clinical studies

      The NIH-NIAID’s Radiation/Nuclear Medical Countermeasures development program is currently testing AEOL 10150 as a
countermeasure for GI-ARS through the Medical Countermeasures Against Chemical Threats (“MCART”) program. The studies are being
funded by the NIAID and are designed to test the efficacy of AEOL 10150 as a treatment for damage to the GI tract due to exposure to
radiation. The study protocols call for the examination of both histological and survival endpoints in mice in a multi-armed vehicle-controlled
trial. For the histological portion, crypt histology will be assessed with crypt number and crypt width being the primary endpoint. Animals
receiving AEOL 10150 began dosing 24 hours after radiation exposure and receive one dose per day for the remainder of the study.
Preliminary results have demonstrated that AEOL 10150 can effectively increase regeneration of GI stem cells, reduce the severity and
duration of diarrhea and improve survival when administered at 24 hours after doses of total-body irradiation that produce the lethal GI
syndrome. The studies are being conducted by Epistem, Ltd. in compliance with criteria of the FDA that are a pre-requisite for movement of
our drug along the pathway for FDA licensure to treat lethally irradiated persons in the event of a terrorist nuclear act. Epistem, Ltd. operates a
major contract research organization and provides services to identify novel drugs that can protect or improve the repair of the GI tract
following exposure to irradiation and performs these studies as part of NIH’s program for the screening of novel agents for bio-defense
applications.

    At a development meeting held in the fourth quarter of 2010, MCART reviewed the results of the two mouse studies that have been
conducted with AEOL 10150 to date and concluded:

1)               AEOL10150 is biologically active as a countermeasure (specifically for GI-ARS)
2)               Based on the fact that all of the animals in the control group died, the level of radiation exposure (13 Gy and 15 Gy) was too
                 high for the study, and a lower level of exposure that generates a mortality rate of 50 to 70 percent would be more appropriate
                 to examine efficacy.
3)               Epistem, Ltd. will conduct a radiation dose range study in which they will look at exposing animals to radiation between 9 and
                 12 Gy.

     During the past twelve months, MCART completed the radiation dose range study work and determined the survival curve for GI ARS in
the C57LJ mouse at the D30, LD50 and LD70 levels. Additionally, MCART completed radiation dose range work in NHPs and determined
the survival curve at the LD30, LD50 and LD70 levels. The results supported the conclusion that radiation exposure of 13 Gy and 15 Gy was
above the optimal exposure levels for an appropriate study to examine efficacy.

    We are unaware of any published studies of agents that accomplish this enhanced stem cell regenerative effect while maintaining GI
function and improving survival when administered post irradiation.

Future Development Plans

    In collaboration with the NIH-NIAID, we are planning additional studies to confirm the efficacy results demonstrated in the study
described above. NIH-NIAID plans to initiate confirmatory efficacy studies of AEOL 10150 in both the murine and NHP models at the
appropriate LD50’s during fiscal year 2012. We also expect to perform additional studies which could be funded by NIH-NIAID to optimize
dose and duration of delivery, and to evaluate the window of opportunity for treatment after exposure.


                                                                          52
     Upon completion of these studies we would need to demonstrate efficacy in animal models and demonstrate product safety based upon the
FDA’s “Animal Rule”. We also plan on pursuing Fast Track submission status for this indication, enabling rolling NDA submission process
and a key step in achieving Priority Review, if accepted by the FDA. The FDA determines within 45 days of a company’s request, made once
the complete NDA is submitted, whether a Priority or Standard Review designation will be assigned. Under the “Animal Rule,” we would need
to complete pivotal studies in two species relevant to the human radiation response and its treatment. We believe that these studies can be
completed using existing validated models for both murine and NHP. This study design would also mimic real world conditions in which it is
anticipated that many of those exposed to radiation will benefit from some shielding (e.g., from cars, buildings, etc.), which will protect some
bone marrow and allow for survival without a bone marrow transplant.

     We will also demonstrate product safety using the same product and formulation used in the animal efficacy trials and proposed for use in
humans. Demonstration of safety includes preclinical demonstration of safety via the standard pre-clinical studies and analyses methods and
Phase I safety trials sufficient to demonstrate product safety in the target patient population. We believe our safety studies completed as a
therapy for ALS and those to be performed under our Lung-ARS contract with BARDA will be more than adequate to demonstrate safety for
this indication.

Competition

     We are unaware of any compounds that protect crypt cells and that increase survival when given to animals exposed to radiation at levels
greater than 10 Gys and given after exposure. There are several companies developing drug candidates that have shown efficacy when given
prior to exposure or at lower levels of radiation.

     However, in general, we face significant competition for U.S. government funding for both development and procurements of medical
countermeasures for biological, chemical and nuclear threats, diagnostic testing systems and other emergency preparedness countermeasures.
The U.S. federal government has currently allocated a significant amount of research funding to the development of countermeasures against
the effects of radiation exposure. As a result, there are many drug candidates under development as a possible countermeasure against the
effects of radiation exposure.

Funding Options

    AEOL 10150 as an MCM for GI-ARS is being tested by our research partners under funding from NIH-NIAID.

AEOL 10150 as a potential medical countermeasure against the effects of chlorine gas

Overview

     Chlorine gas is a toxic gas that confers airway injury through primary oxidative stress and secondary inflammation. Chlorine inhalation
was recently used in terrorist/insurgent attacks on military and civilian populations, and has caused numerous industrial, transportation,
swimming pool, and household accidents, as well as deaths to members of the U.S. military in the past. Chlorine gas, also known as bertholite,
was first used as a weapon in World War I. Chlorine gas was also used against the local population and coalition forces in the first Iraq War in
the form of chlorine bombs.

     The increased risk of a terrorist attack in the United States involving chemical agents has created new challenges for many departments
and agencies across the federal government. Within the HHS, the NIH is taking a leadership role in pursuing the development of new and
improved medical countermeasures designed to prevent, diagnose, and treat the conditions caused by potential and existing chemical agents of
terrorism. In addition, many of the same chemicals posing a threat as terrorist agents may also be released from transportation and storage
facilities by industrial accidents or during a natural disaster. The NIH has developed a comprehensive NIH-CounterACT Research Network
that includes Research Centers of Excellence, individual research projects, small business innovation research, contracts and other programs.
The NIH-CounterACT network is conducting basic, translational and clinical research aimed at the discovery and/or identification of better
therapeutic and diagnostic medical countermeasures against chemical threat agents, and their movement through the regulatory process. The
overarching goal of this research program is to enhance our diagnostic and treatment response capabilities during an emergency.

     Another critical goal of the NIH-CounterACT program is to assist in the development of safe and effective medical countermeasures
designed to prevent, diagnose, and treat the conditions caused by potential and existing chemical agents of terrorism which can be added to the
Nation’s Strategic National Stockpile (“SNS”). The SNS is maintained by the Centers for Disease Control and Prevention (“CDC”). The SNS
now contains CHEMPACKS which are located in secure, environmentally controlled areas throughout the United States available for rapid
distribution in case of emergency. The CDC has established a diagnostic response network for the detection of nerve agents, mustard, cyanide
and toxic metals. The NIH will continue to research, develop and improve medical products that include chemical antidotes, drugs to reduce
morbidity and mitigate injury, drugs to reduce secondary chemical exposure and diagnostic tests and assessment tools to be used in mass
casualty situations.


                                                                       53
     Worldwide, independent of warfare and chemical terrorism, chlorine is the greatest single cause of major toxic release incidents (16.Davis
DS, Dewolf GB, Ferland KA, et al. Accidental Release of Air Toxins. Park Ridge, New Jersey: NDC; 1989:6-9.). In the U.S., there are about
5-6,000 exposures per year resulting in, on average, about one death, 10 major, 400-500 moderate, and 3-4,000 minor adverse outcomes. Like
mustard, chlorine causes damage to upper and lower respiratory tracts. While chlorine is an irritant, its intermediate water solubility may delay
emergence of upper airway symptoms for several minutes. Aqueous decomposition of chlorine gas forms hydrochloric acid and hypochlorous
acid, itself also a product of inflammation. Cell injury is thought to result from oxidation of functional groups in cell components, from tissue
formation of hydrochloric acid and hypochlorous acid, and possibly from formation of other ROS. For treatment of acute exposures in humans,
decontamination, supplemental oxygen, treatment of bronchospasm and/or laryngospasm, and supportive care are the only accepted therapies,
while use of nebulized sodium bicarbonate and parenteral and/or inhaled steroids remain quite controversial. No specific beneficial therapies
are available. We expect that AEOL 10150 will decrease airway injury, inflammation, oxidative damage, hyperreactivity and cell proliferation
after acute chlorine gas inhalation in mice and therefore could be a possible beneficial therapy for chlorine gas inhalation injury to the airways.

Pre-clinical studies

     Under a grant from NIH CounterACT, researchers from NJH and McGill University have completed a series of preliminary studies
demonstrating that AEOL 10150 protects lungs from chlorine gas exposure in mice and rats. The primary objective of these studies was to
determine whether administration of AEOL 10150, after exposure, reduces the severity of acute lung injury and asthma-like symptoms induced
by chlorine gas. AEOL 10150 was given to mice at a 5 mg/kg subcutaneous dose one hour after chlorine gas exposure (100 ppm for 5 minutes)
and repeated every 6 hours. Twenty-four hours after exposure, lung inflammation was assessed by changes in bronchoalveolar lavage (“BAL”)
cellularity and neutrophil influx. AEOL 10150 significantly reduced (p<0.05, n=6/group) chlorine gas-induced lung inflammation as measured
by BAL fluid cellularity levels by 40% that appeared to be due to limiting neutrophil influx. AEOL 10150 also significantly attenuated
(p<0.05, n=6) the degree of asthma-like airway reactivity induced by chlorine gas exposure by 40%. These results indicate that AEOL 10150
can attenuate lung injury and asthma-like symptoms from chlorine gas exposure and may provide an effective countermeasure against chlorine
gas-induced lung injury.

    NJH replicated the mice studies previously conducted by McGill University in rats to determine whether AEOL 10150 mitigates lung
damage due to chlorine gas exposure. In the study, 10150 significantly reduced protein, IgM, white blood cell, red blood cell, macrophage and
neutrophil counts in Broncho-alveolar lavage fluid.

Future Development Plans

    Under a new $12.5 million grant received from NIH CounterACT in September 2011, NJH plans to complete studies in 2012 to determine
whether the initiation of treatment with AEOL 10150 can be delayed to 24 hours or later. Additionally, studies will be run to examine the
longer term effect of chlorine gas exposure and AEOL 10150’s ability to mitigate those effects. Upon completion of these studies, the
Company plans to file an IND for Chlorine Gas exposure with the FDA.

    Following these studies, and provided we received sufficient funding for the program, we seek to develop a second animal model and to
launch the two pivotal efficacy studies required for approval by the FDA under the “Animal Rule”. The Company believes that the safety and
CMC work being done under the BARDA Lung-ARS further described under the heading “AEOL 10150 as a potential medical
countermeasure against the effects of acute radiation syndrome in the lungs – Future Development Plans” will be sufficient to satisfy the safety
and CMC requirements for an NDA filing.

Competition

     There are currently no effective treatments for chlorine gas exposure and AEOL 10150 is a major focus of the NIH-CounterACT program
to identify an effective treatment.

     However, in general, we face significant competition for U.S. government funding for both development and procurements of MCMs for
biological, chemical and nuclear threats, diagnostic testing systems and other emergency preparedness countermeasures. The U.S. federal
government has currently allocated a significant amount of research funding to the development of countermeasures against bioterrorism. As a
result, there are many drug candidates under development as a possible countermeasure against chemical threat agents.


                                                                        54
Funding Options

   Currently, the development of AEOL 10150 as a potential MCM against the effects of chlorine gas is being funded by the
NIH-CounterACT program.

     In May of 2010, we submitted a white paper to BARDA in response to a Broad Agency Announcement (BAA-BARDA-100-SOL-0012)
for advanced research and development of MCM for chemical, biological, radiological and nuclear threats, seeking potential countermeasures
for chemical agents.

    On December 10, 2010, we submitted a full proposal to BARDA for the development of AEOL 10150 as a medical countermeasure for
chlorine gas exposure. The proposal sought funding to take the compound from its current state to FDA approval over a three year period. On
June 28, 2011, BARDA informed us that it would not be entering into negotiation with us for the development of the chlorine indication at this
time, but invited us to resubmit our proposal after completion of some of the safety and efficacy studies in our current Lung-ARS program
funded by BARDA. BARDA indicated in its response that there was some overlap in the development program proposed and the current
BARDA Contract, and that it was already funding the radiation indication, which is a very similar program.

     In October 2011, we announced that NJH was awarded a $12.5 million contract from NIH-CounterACT to continue the development of
AEOL 10150 as a MCM against chlorine gas exposure. Also included in the grant is support of research looking at tissue plasminogen activator
(TPA) and Silabilin as MCMs against sulfur mustard gas exposure. The ultimate objective of the sulfur mustard and chlorine gas work at NJH
will be to complete all work necessary to initiate pivotal efficacy studies for both indications. This would include: running efficacy studies in
the rat model for higher doses of sulfur mustard and chlorine gas; establishing endpoints, optimal dosing and duration of treatment for pivotal
efficacy studies; and characterizing the natural history from sulfur mustard and chlorine gas damage.

AEOL 10150 as a potential medical countermeasure against the effects of mustard gas

Overview

     Sulfur mustards, of which mustard gas is a member, are a class of related cytotoxic, vesicant chemical warfare agents with the ability to
form large blisters on exposed skin and cause pneumonitis and fibrosis in the lungs. In their pure form most sulfur mustards are colorless,
odorless, viscous liquids at room temperature. When used as warfare agents they are usually yellow-brown in color and have an odor
resembling mustard plants, garlic or horseradish. Mustard agents, including sulfur mustard, are regulated under the 1993 Chemical Weapons
Convention. Three classes of chemicals are monitored under this Convention, with sulfur and nitrogen mustard grouped in the highest risk
class, “schedule 1”.However, concerns about its use in a terrorist attack have led to resurgence in research to develop a protectant against
exposure.

     Mustard gas is a strong vesicant (blister-causing agent). Due to its alkylating properties, it is also strongly mutagenic (causing damage to
the DNA of exposed cells) and carcinogenic (cancer causing). Those exposed usually suffer no immediate symptoms. Within 4 to 24 hours the
exposure develops into deep, itching or burning blisters wherever the mustard contacted the skin; the eyes (if exposed) become sore and the
eyelids swollen, possibly leading to conjunctivitis and blindness. At very high concentrations, if inhaled, it causes bleeding and blistering
within the respiratory system, damaging the mucous membrane and causing pulmonary edema. Blister agent exposure over more than 50%
body surface area is usually fatal.

     The NIH awarded a five-year, $7.8 million grant to NJH and the University of Colorado Health Sciences Center, both in Denver,
Colorado. This Center of Excellence was developed to focus on sulfur mustard toxicity in the lung and skin with the long-term goal to develop
an effective treatment for mustard gas induced injury in lung and skin. Members of the Center are establishing optimal compounds, route and
mode of delivery. Research projects are ongoing to determine countermeasures that will help establish specific interventions needed to rescue
mustard gas-induced injury. After three years of research, AEOL 10150 has been identified by the NJH Center of Excellence as a lead
compound for its center, and research work there has been focused on further testing and studies of AEOL 10150.


                                                                       55
     Research in the area of mustard gas-mediated lung injury has provided experimental evidence that the mechanisms of these injuries are
directly linked to the formation of reactive oxygen and nitrogen species and that superoxide dismutase and catalase can improve injury
responses. This theory has led to the hypothesis that the administration of catalytic antioxidant therapy can protect against mustard gas-induced
acute lung and dermal injury. AEOL 10150 has already been shown to be well tolerated in humans and could be rapidly developed as a drug
candidate in this area pending animal efficacy data.

    Researchers have found that the chemical warfare agent analog, 2-chloroethyl ethyl sulfide (“CEES”)-induced lung injury could be
improved by both exogenous superoxide dismutase and catalase. Both of these natural enzymes are important catalytic antioxidants and both of
these reactions are exhibited by metalloporphyrins. CEES-induced lung injury is dependent in part upon blood neutrophils. Activated
neutrophils are an important source of reactive oxygen species that are known to contribute to lung injury responses. Antioxidants have also
been shown to protect against CEES-induced dermal injury. Mustard exposure is often associated with producing acute respiratory distress
syndrome that requires supplemental oxygen therapy to maintain adequate tissue oxygenation.

    Further studies revealed that AEOL 10150 was effective at diminishing life-threatening airway obstruction produced by high dose
exposure of CEES in rats with AEOL 10150 rescue providing substantial improvements in blood gas oxygen saturation, decreased airway
obstruction and inflammation.

Pre-clinical studies

    A study performed by researchers from NJH demonstrated that AEOL 10150 showed statistically significant protection of lung tissue in
animals exposed to CEES or half-mustard. In a study sponsored by the NIH-CounterACT program, AEOL 10150 was tested along with 19
other compounds to determine effectiveness in protecting lung tissue against edema and hemorrhage resulting from exposure to mustard gas.

     AEOL 10150 was given to rats one hour after CEES exposure and again 6 hours later. Eighteen hours after exposure, lung edema and
hemorrhage was assessed by changes in the bronchoalveolar lavage protein and red blood cell levels. AEOL 10150 significantly reduced
(p<0.05) mustard gas-induced lung edema and hemorrhage. These results suggest that AEOL 10150 rescues the lung from mustard gas
exposure and may provide a countermeasure against mustard gas-induced lung injury. Further studies at NJH and the University of Colorado
showed that doses in the range of 5 to 30 mg/kg of AEOL 10150 given at one and eight hours after exposure mitigate both lung and skin injury
in animal models. Doses in the range of 5 to 10 mg/kg/d showed the most potent effect including significant mitigation as assessed by
histopathology and immunohistochemistry.

Non-clinical studies

     In 2009, several studies were launched to test the efficacy of AEOL 10150 as a treatment for damage to the skin and lungs due to exposure
to sulfur mustard gas and to examine potential effective doses, duration of delivery and the window of opportunity for treatment after exposure.
The studies are being conducted using “whole” sulfur mustard gas at Lovelace Respiratory Research Institute, another NIH-CounterACT
Center of Excellence, and using data obtained from CEES studies at NJH and build on results from previous studies using CEES conducted at
NJH and the University of Colorado.

     The first whole mustard gas study was completed in October 2009.The study demonstrated that AEOL 10150 protects lungs from whole
mustard gas exposure in rats. The data affirmed our earlier studies where AEOL 10150 protected the lung against the half-mustard, CEES. The
primary objective of the studies was to determine whether administration of AEOL 10150, after exposure, reduces the severity of acute lung
injury induced by mustard gas. AEOL 10150 was given to rats one hour after sulfur mustard exposure and repeated every 6 hours. Twenty-four
hours after exposure, lung edema was assessed by changes in the BAL protein levels. AEOL 10150 significantly reduced (p<0.05) mustard
gas-induced lung edema as measured by BAL protein levels. In addition, AEOL 10150 decreased SM-induced increase in the numbers of BAL
neutrophils. These results indicate that AEOL 10150 can attenuate lung injury from mustard gas exposure and may provide an effective
countermeasure against mustard gas-induced lung injury.

     In June 2010, NJH and Lovelace Respiratory Research Institute reported results from a second whole mustard study confirming that AEOL
10150 protects lungs from whole mustard gas exposure in rats. The primary objective of this study was to determine whether administration of
AEOL 10150, after exposure, reduces the severity of acute lung injury induced by mustard gas. AEOL 10150 was given to rats one hour after
sulfur mustard vapor exposure and repeated every 6 hours. Twenty-four hours after exposure, lung edema was assessed by changes in the BAL
protein levels. AEOL 10150 significantly reduced (p<0.05) mustard gas-induced lung edema as measured by bronchoalveolar lavage protein
levels. In addition, AEOL 10150 decreased SM-induced increases in macrophages (p<0.05) and epithelial cells in BAL fluid (P<0.05).In all
three measurements AEOL 10150 provided approximately 100 percent protection – with levels approximating that of the control animals in the
study. These results indicate that AEOL 10150 can attenuate lung injury from mustard gas exposure and may provide an effective
countermeasure against mustard gas-induced lung injury.


                                                                       56
Future Development Plans

    Following these confirmatory studies, we seek to launch the two pivotal efficacy studies required for approval by the FDA under the
“Animal Rule” as well as complete the necessary safety studies as further described under the heading “AEOL 10150 as a potential medical
countermeasure against the effects of acute radiation syndrome in the lungs – Future Development Plans – Demonstrate Product Safety.”

Competition

    There are currently no effective treatments for mustard gas exposure and AEOL 10150 is a major focus of a sponsored research grant
awarded by the NIH-CounterACT program to NJH to identify an effective treatment.

     However, in general, we face significant competition for U.S. government funding for both development and procurements of medical
countermeasures for biological, chemical and nuclear threats, diagnostic testing systems and other emergency preparedness countermeasures.
The U.S. federal government has currently allocated a significant amount of research funding to the development of countermeasures against
bioterrorism. As a result, there are many drug candidates under development as a possible countermeasure against chemical threat agents.

Funding Options

    This development program to date has been funded under the NIH-CounterACT Program and we expect that future efficacy studies
necessary for approval by the FDA will also be funded by the NIH-CounterACT program.

AEOL 10150 in Radiation Therapy

Overview

          According to the American Cancer Society, cancer is the second leading cause of death by disease, representing one out of every four
deaths in the United States. Approximately 572,000 Americans were expected to die of cancer in 2011. In 2011, about 1.6 million new cancer
cases are expected to be diagnosed in the United States. According to the Radiological Society of North America, about 50 to 60 percent of
cancer patients are treated with radiation at some time during their disease. The NIH estimated overall costs of cancer in 2008 in the United
States at $228.1 billion, $93.2 billion for direct medical costs, $18.8 billion for indirect morbidity costs (costs of lost productivity due to illness)
and $116.1 billion for indirect mortality costs (cost of lost productivity due to premature death).

         Combinations of surgery, chemotherapy and radiation treatments are the mainstay of modern cancer therapy. Success is often
determined by the ability of patients to tolerate the most aggressive, and most effective, treatment regimens. Radiation therapy-induced toxicity
remains a major factor limiting radiation doses. The ability to deliver maximal radiation doses for treatment of tumors without injury to
surrounding normal tissue has important implications in oncology therapeutic outcomes because higher doses of radiation therapy may improve
both local tumor control and patient survival.

         Advances in the tools of molecular and cellular biology have enabled researchers to develop a better understanding of the underlying
mechanisms responsible for radiation therapy-induced normal tissue injury. For decades ionizing radiation has been known to increase
production of free radicals, which is reflected by the accumulation of oxidatively damaged cellular macromolecules.

          As one example of rad iation-induced damage to adjacent normal tissue, radiation therapy may injure pulmonary tissue either directly
via generation of ROS or indirectly via the action on parenchymal and inflammatory cells through biological mediators such as TGF -β and
pro-infl ammatory cytokines. Since the discovery of SOD, it has become clear that these enzymes provide an essential line of defense against
ROS. SODs and SOD mimics, such as AEOL 10150, act by catalyzing the degradation of superoxide radicals into oxygen and hydrogen
peroxide. SODs are localized intra/extracellularly, are widely expressed throughout the body, and are important in maintenance of redox status
(the balance between oxidation and reduction).Previous studies have demonstrated that treating irradiated animal models with SOD delivered
by injection of the enzyme through liposome/viral-mediated gene therapy or insertion of human SOD gene can ameliorate radiation
therapy-induced damage. For an illustrative example of the radiation therapy reaction see Figure 2.


                                                                          57
                                                                     Figure 9




Figure 9 above shows the dual mechanism of action of radiation therapy and the application of AEOL 10150 to the process.

     In vitro studies have demonstrated that AEOL 10150 reduces the formation of lipid peroxides and that it inactivates biologically important
ROS molecules such as superoxide, hydrogen peroxide and peroxynitrite. AEOL 10150 inactivates these ROS by one or two electron oxidation
or reduction reactions in which the oxidation state of the manganese moiety in AEOL 10150 changes. AEOL 10150 is not consumed in the
reaction and it continues to inactivate such ROS molecules as long as it is present at the target site. Preclinical models and human safety studies
suggest AEOL 10150 is not metabolized in the body and is excreted in feces and urine.




                                                                        58
Pre- clinical studies

                                                                    Figure 10




Figure 10 .Relative tumor volumes of human prostate tumor implants in nude mice: Implants of well-vascularized PC3 tumors were grown to
substantial size prior to receiving fractionated radiation (5 Gy daily for three days).AEOL 10150 (7.5 mg/kg/bid) was administered
subcutaneously commencing on the first day of irradiation and continued for 20 days. Other groups of mice received either no irradiation,
irradiation only or AEOL 10150 without irradiation.

Due to the similar mechanisms of actions between radiation therapy (in oncology) and radiation exposure (from nuclear events), we believe
that the pre-clinical studies performed for the development of AEOL 10150 as a potential medical countermeasure against the effects of
Lung-ARS, as described below, also provide support for the development of AEOL 10150 in oncology, to be used in combination with
radiation therapy.

     We have performed several additional studies specifically for this indication to ensure the use of an antioxidant in radioprotection of
normal adjacent tissue does not interfere with the efficacy of tumor radiotherapy. A number of preclinical, in vivo studies have addressed this
issue and have demonstrated that AEOL 10150 does not negatively impact tumor radiotherapy.

     In one study (Vujaskovic, et al. of Duke University), human prostate tumors (PC3) grown in nude mice to substantial size were fraction
irradiated with 5 Gy per day for 3 days for a total of 15 Gy. AEOL 10150 at 7.5 mg/kg/bid was administered subcutaneously on the first day of
radiation and continued for either of two time courses: when tumor volume reached 5 times the initial volume or for twenty days. The receding
tumor volume curves for irradiation only and for irradiation plus AEOL 10150 were super-imposable. Therefore AEOL 10150 did not interfere
with the radiation effect on xenogenic prostate tumor.

     In another study of prostate cancer tumors (Gridley, et al of Loma Linda University), mouse prostate cancer cell line RM-9 was injected
subcutaneously into C57/Bl6 mice, followed by up to 16 days of AEOL 10150 delivered intraperitonealy at 6 mg/kg/day. On day seven, a
single non-fractionated dose of radiation (10 Gy) was delivered. Therefore, the mice received compound for seven days prior to radiation. The
results of this study demonstrated that AEOL 10150 does not protect the prostate tumor against radiation, and, in fact, AEOL 10150 showed a
trend towards increasing the effectiveness of the radiation treatment. The primary effect appears to be in down-regulation of radiation induced
HIF-1 expression and VEGF and up-regulation of IL-4.Thus, AEOL 10150, through its down-regulation of VEGF, may inhibit formation of
blood vessels (i.e., angiogenisis) required for tumor re-growth and protects normal tissues from damage induced by radiation and
chemotherapy.

     In another study (Vujaskovic, et al. of Duke University), mice were implanted with human NSCLC tumors and treated with all potential
combinations of paclitaxel, radiation and AEOL 10150 to determine the impact on tumor growth. The results showed that AEOL 10150 did
not impact the effects of either radiation therapy or paclitaxel. Further, the study indicated that the greatest impact in inhibiting tumor growth
was with the regimen that included all three (radiation + paclitaxel + AEOL10150).



                                                                        59
                                                                 Figure 11




    Figure 11 above measures tumor volume against time after implantation of RM-9 tumor cells and shows that AEOL 10150 treatment
resulted in inhibition of tumor re-growth in a study performed by Dr. Gridley of Loma Linda University. Daily intraperitoneal injections of
AEOL 10150 were initiated on day 1.At 12 days, approximately one half of each tumor-bearing group and control mice with no tumor were
euthanized for in vitro analyses; remaining mice/group were followed for tumor growth and euthanized individually when maximum allowed
tumor volume was attained. Each point represents the mean +/- standard error of the mean. Two-way analysis of the variance for days 8 to 14
revealed that group and time had highly significant main effects (Ps<0.001) and a group x time interaction was noted (P<0.001).


                                                                 Figure 12




    Figure 12 above shows the HIF-1 Expression in prostate tumors and the impact of the treatment of AEOL 10150 in a study by Dr. Gridley
of Loma Linda University.

                                                                    Figure 13




   Figure 13 above shows impact on tumor growth in mice that were implanted with human NSCLC tumors and treated with all potential
combinations of paclitaxel, Radiation and AEOL 10150.

    The data obtained in these preclinical studies suggest that the post-irradiation, long-term delivery of AEOL 10150 may be protective
against radiation-induced lung injury, as assessed by histopathology and immunohistochemistry. Oxidative stress, inflammation and hypoxia,
which play important roles in the pathogenesis of radiation mediated fibrosis, were shown to be reduced in animals treated with higher doses of
AEOL 10150.Studies have also shown that AEOL 10150 does not adversely impact tumor response to radiation therapy. Thus, treatment with
AEOL 10150 does not significantly protect tumors from the cell killing effects of radiation therapy. This combined with other studies that have
shown that AEOL 10150 significantly prevents radiation induced normal tissue injury suggests that AEOL 10150 has the potential to achieve
normal tissue protection without protection of tumor tissue. Additionally, it appears the down-regulation of radiation induced HIF-1 expression
and VEGF and up-regulation of IL-4 may provide additional anti-tumor effects. Thus, AEOL 10150, through its down-regulation of VEGF,
may inhibit formation of blood vessels required for tumor re-growth, while protecting normal tissues from damage induced by radiation and
chemotherapy.

Future Development Plans

     We are leveraging the significant investment made by U.S. government agencies to develop this promising compound for use in oncology
indications, where it would be used in combination with chemotherapy and radiation therapy, and is currently in development for use as both a
therapeutic and prophylactic drug. Data has already been published showing that AEOL 10150 does not interfere with the therapeutic benefit of
radiation therapy in prostate and lung cancer preclinical studies.

    In fiscal year 2012, the Company expects to initiate a safety study in healthy normal volunteers under the BARDA Lung-ARS
contract. Upon the successful completion of the Phase I study and approval of its protocol by the FDA and the appropriate IRBs, we expect to
begin a Phase II study in NSCLC patients.

Competition

     There are currently three drugs approved for the treatment of the side effects of radiation therapy. We do not believe that any of these
drugs directly competes with AEOL 10150 in terms of mechanism of action or targeted therapeutic benefit when used in combination with
radiation therapy.

    Amifostine (Ethyol®) is approved by the FDA as a radioprotector. Amifostine (Ethyol) is marketed by MedImmune, Inc. for use in
reduction of chemotherapy-induced kidney toxicity associated with repeated administration of cisplatin in patients with advanced ovarian
cancer and radiation-induced xerostomia (damage to the salivary gland) in patients undergoing post-operative radiation treatment for head and
neck cancer. MedImmune, Inc. is studying Amifostine in other indications of radiation therapy. KepivanceTM (palifermin) is marketed by
Amgen, Inc. for use in the treatment of severe oral mucositis (mouth sores) in patients with hematologic (blood) cancers who are undergoing
high-dose chemotherapy followed by bone transplant. Amgen, Inc. is also studying Kepivance as an antimucositis agent in patients with head
and neck cancer, non-small cell lung cancer and colon cancer. Salagen Tablets (pilocarpine hydrochloride) is marketed by Eisai
Pharmaceuticals in the United States as a treatment for the symptoms of xerostomia induced by radiation therapy in head and neck cancer
patients. In addition, there are many drugs under development to treat the side effects of radiation therapy.


                                                                     61
Funding Options

    Substantially all of our costs associated with the CMC and toxicology necessary for the oncology indications, plus human safety studies in
humans, have been, or we expect will be, covered by the BARDA Contract. We expect such costs to continue to be covered by the BARDA
Contract. If BARDA chooses not to exercise its options under the BARDA Contract, then we would need to raise additional capital, or partner
with another firm, in order to complete the non-clinical and safety programs noted above. We will need to internally fund the human efficacy
programs in oncology, as well as any non-clinical studies that may be necessary for specific oncology indications. We may still seek to raise
capital through other sources even if BARDA exercises one or more of the options under the BARDA Contract.

AEOL 10150 in Amyotrophic Lateral Sclerosis

Overview

    ALS, commonly referred to as “Lou Gehrig’s disease,” the most common motor neuron disease, results from progressive degeneration of
both upper and lower motor neurons. Motor Neuron Disease (“MND”) is an all-embracing term used to cover a number of illnesses of the
motor neuron. ALS, Progressive Muscular Atrophy (PMA), Progressive Bulbar Palsy (PBP), Primary Lateral Sclerosis (PLS) are all subtypes.
MND is the generic term for this disease and is used more frequently in Europe, while ALS is used more frequently in the U.S.

     According to the ALS Association (“ALSA”), the incidence of ALS is two per 100,000 people. ALS occurs more often in men than
women, with typical onset between 40 and 70 years of age. ALS is a progressive disease and approximately 80% of ALS patients die within
five years of diagnosis, with only 10% living more than 10 years. The average life expectancy is two to five years after diagnosis, with death
from respiratory and/or bulbar muscle failure. The International Alliance of ALS/MND Associations reports there are over 350,000 patients
with ALS/MND worldwide and 100,000 people die from the disease each year worldwide. In the United States, ALSA reports that there are
approximately 30,000 patients with ALS with 5,600 new patients diagnosed each year.

     Sporadic (i.e., of unknown origin) ALS is the most common form, accounting for approximately 90% of cases. The cause of sporadic ALS
is unclear. Familial ALS comprises the remainder of cases and 5-10% of these patients have a mutated superoxide dismutase 1 (“SOD1”) gene.
More than 90 point mutations have been identified, all of which appear to associate with ALS, and result in motor neuron disease in
corresponding transgenic mice. SOD mutations have been observed in both familial and sporadic ALS patients, although the nature of the
dysfunction produced by the SOD1 mutations remains unclear. The clinical and pathological manifestations of familial ALS and sporadic ALS
are indistinguishable suggesting common pathways in both types of disease.

    In November 2003, the FDA granted orphan drug designation for our ALS drug candidate. Orphan drug designation qualifies a product for
possible funding to support clinical trials, study design assistance from the FDA during development and for financial incentives, including
seven years of marketing exclusivity upon FDA approval.

Pre-clinical studies

     John P. Crow, Ph.D., and his colleagues at the University of Alabama at Birmingham tested AEOL 10150 in an animal model of ALS
(SOD1 mutant G93A transgenic mice).The experiments conducted by Dr. Crow (now at the University of Arkansas College of Medicine) were
designed to be clinically relevant by beginning treatment only after the onset of symptoms in the animals is observed. Twenty-four confirmed
transgenic mice were alternately assigned to either a control group or AEOL 10150-treatment on the day of symptom onset, which was defined
as a noticeable hind-limb weakness. Treatment began on the day of symptom onset. The initial dose of AEOL 10150 was 5 mg/kg, with
continued treatment at a dose of 2.5 mg/kg once a day until death or near death.

    Table 1 and Figure 14 above show that AEOL 10150 treatment resulted in a greater than 2.5 times mean survival interval, compared to
control. AEOL 10150-treated mice were observed to remain mildly disabled until a day or two before death. In contrast, control mice
experienced increased disability daily.

     Dr. Crow has repeated the ALS preclinical experiment a total of four times, in each case with similar results. The efficacy of AEOL 10150
in the G93A mouse model of ALS has also been evaluated by two additional laboratories. One of these laboratories verified an effect of AEOL
10150 in prolonging survival of the G93A mouse, while no beneficial effect of the drug was identified in the other laboratory.

Future Development Plans

    We do not currently have any plans to pursue the development of AEOL 10150 for the treatment of ALS unless we are able to obtain
funding specifically for this purpose.

Competition

    Rilutek® (riluzole), marketed by Sanofi-Aventis SA, is the only commercially approved treatment for ALS in the United States and the
European Union. Administration of Rilutek prolongs survival of ALS patients by an average of 60-90 days, but has little or no effect on the
progression of muscle weakness, or quality of life. Rilutek was approved in the United States in 1995, and in 2001 in the European Union.
However, there are at least twenty drug candidates reported to be in clinical development for the treatment of ALS.

    In addition, ALS belongs to a family of diseases called neurodegenerative diseases, which includes Alzheimer’s, Parkinson’s and
Huntington’s disease. Due to similarities between these diseases, a new treatment for one ailment potentially could be useful for treating others.
There are many companies that are producing and developing drugs used to treat neurodegenerative diseases other than ALS.


                                                                       63
AEOL 10150 Clinical Development Program

     AEOL 10150 has been thoroughly tested for safety, tolerability and pharmacokinetics with no serious or clinically significant adverse
effects observed. To date, 38 patients have received AEOL 10150 in three clinical trials designed to test the safety and tolerability of the drug
candidate.

     In September 2005, we completed a multi-center, double-blind, randomized, placebo-controlled, Phase I clinical trial. This escalating-dose
study was conducted to evaluate the safety, tolerability and pharmacokinetics of AEOL 10150 administered by twice daily subcutaneous
injections in patients with ALS.

     In the Phase Ia study, 4-5 patients diagnosed with ALS were placed in a dosage cohort (3 or 4 receiving AEOL 10150 and 1 receiving
placebo).Each dose cohort was evaluated at a separate clinical center. In total, seven separate cohorts were evaluated in the study, and 25 ALS
patients received AEOL 10150. Based upon an analysis of the data, it was concluded that single doses of AEOL 10150 ranging from 3 mg to
75 mg were safe and well tolerated. In addition, no serious or clinically significant adverse clinical events were reported, nor were there any
significant laboratory abnormalities. Based upon extensive cardiovascular monitoring (i.e., frequent electrocardiograms and continuous Holter
recordings for up to 48 hours following dosing), there were no compound-related cardiovascular abnormalities.

    The most frequently reported adverse events in this Phase I clinical trial were injection site reactions, followed by dizziness and headache.
Adverse events were primarily mild in severity, and approximately one-half of the events were considered to have a possible relationship to the
study medication. In addition, no clinically meaningful findings were noted in the safety, laboratory, vital sign, the Unified Parkinson’s Disease
Rating Scale (“UPDRS”), functional ALS, or electro cardiogram (“ECG”) data. All cohorts exhibited dose-related peak plasma drug
concentrations and consistent disappearance half-lives.

     In October 2006, we completed a multi-center, double-blind, randomized, placebo-controlled, Phase Ib clinical trial. This multiple dose
study was conducted to evaluate the safety, tolerability and pharmacokinetics of AEOL 10150 administered by subcutaneous injection and
infusion pump in patients with ALS. Under the multiple dose protocol, three groups of six ALS patients (four receiving AEOL 10150 and two
receiving placebo) were enrolled, based upon patients who meet the El Escorial criteria for Clinically Definite ALS, Clinically Probable ALS,
Clinically Probable-Laboratory Supported ALS, or Definite Familial-Laboratory Supported ALS (i.e., Clinically Possible ALS with an
identified SOD gene mutation).

     The first two cohorts of the Phase Ib multiple dose study received a fixed daily dose of AEOL 10150 twice a day by subcutaneous
injection. In the first cohort, each patient received twice daily subcutaneous injections of 40 mg of AEOL 10150 or placebo, for six consecutive
days, followed by a single subcutaneous injection on the seventh day, for a total of 13 injections. In the second cohort, each patient received
twice daily subcutaneous injections of 60 mg of AEOL 10150 or placebo, for six consecutive days, followed by a single subcutaneous injection
on the seventh day, for a total of 13 injections.

     In contrast, the third cohort received a weight adjusted dose (i.e., mg per kilogram of body weight per day) delivered subcutaneously over
twenty four hours by continuous infusion pump. In the third cohort, each patient received AEOL 10150 via continuous infusion pump for six
and one half consecutive days for a total of 2.0 mg per patient kilogram per day. Each patient in all three cohorts completed the study and
follow-up evaluation at 14 days.

    The Phase Ib study was conducted at five academic clinical ALS centers. Male and female ALS patients, 18 to 70 years of age, who were
ambulatory (with the use of a walker or cane, if needed) and capable of orthostatic blood pressure assessments were enrolled in the study.
Clinical signs/symptoms, laboratory values, cardiac assessments and pharmacokinetics (PK) were performed.

     Based upon an analysis of the data, it was concluded that multiple doses of AEOL 10150 for a period of six and one half consecutive days
in the amount of 40 mg per day, 60 mg per day and 2 mg per kilogram per day were safe and well tolerated. No serious or clinically significant
adverse events were reported or observed. The most frequent adverse events related to study compound were injection site observations related
to compound delivery. There were no significant laboratory abnormalities. Based upon extensive cardiovascular monitoring (i.e., frequent
electrocardiograms and continuous Holter recordings throughout the six and one half days of dosing), there were no compound-related
cardiovascular abnormalities.


                                                                        64
    Pharmacokinetic findings from the Phase Ib study to date are as follows:

             ● Increases in Cmax and AUC (0-8) appear to correlate with increases in dose, but the correlation is not strong.
             ● The mean Cmax for the 40 mg cohort was 1,735 ng/mL; 2,315 ng/mL for the 60 mg cohort and 1,653 ng/mL for the 2 mg/kg
                  cohort.
             ● There were probable linear correlations between both Cmax and AUC(0-8) and dose based on body weight.
             ● The terminal half-life (a measurement of the time period for which a compound stays in the body) as determined from Day 7
                  data was approximately 8 to 9 hours.
             ● Steady-state occurs within three days of multiple dosing. There was no evidence for a third longer half-life that would be
                  associated with long term accumulation. Thus, compound accumulation is not expected beyond the third day with multiple
                  dosing.
             ● From 48 hours to the end of the infusion, the plasma concentrations of AEOL 10150 during the infusion showed little
                  variability, indicating a smoother delivery of the drug than with twice-daily injections.

     During 2008, we completed a follow-on Phase I open label compassionate use multiple dose study of AEOL 10150 in a patient diagnosed
with progressive and debilitating amyotrophic ALS. The study was conducted at the University of California, Los Angeles by Martina
Wiedau-Pazos, M.D., and was designed to evaluate the safety and efficacy of AEOL 10150 in an ALS patient over an extended period of time.
The patient received a subcutaneous injection of 75mg of AEOL 10150 two times each day for 34 days. Efficacy and safety data was monitored
for the duration of the study. The primary objective of this study was to assess the clinical efficacy of AEOL 10150 with respect to the patient’s
baseline assessment of functional status. Secondary objectives included the assessments of muscle strength, respiratory function, quality of life
and safety. The patent’s baseline efficacy results were an ALS Functional Rating Scale (“ALSFRS-R”) rating of 19, Muscle strength Manual
Muscle Testing Scale (“MMTS”) of 68 and a forced vital capacity (“FVC”) of 30%. The patient’s results after 2 months were an ALSFRS-R
rating of 22, a MMTS rating of 86 and an FVC of 28%. It should be noted that the subject began using breathing assistance (BiPAP)
approximately two weeks after the study started. The patient discontinued treatment due to nausea and moderately increased liver
transaminases. Other drug-associated adverse events included mild skin irritation at the injection site and mild urine discoloration.

 AEOL 11207

Overview

     We have selected AEOL 11207 as our second development candidate based upon results from data obtained from our pre-clinical testing
of our pipeline drug candidates. Because of the wide-ranging therapeutic opportunities that the compound evidenced in diverse pre-clinical
models of human diseases, we have not yet ascertained what the most robust therapeutic use of AEOL 11207 might be. However, data
collected to date suggest that AEOL 11207 may be useful as a potential once-every-other-day oral therapeutic treatment option for central
nervous system (“CNS”) disorders, most likely Parkinson’s disease.

    Parkinson’s disease is a common neurodegenerative disorder, second in occurrence among these disorders only to Alzheimer’s disease.
According to the National Parkinson Foundation, Parkinson’s affects as many as one million people in the United States, with approximately
60,000 new cases diagnosed in the United States each year.

     Parkinson’s specifically involves the progressive destruction of the nerves that secrete dopamine and control the basal ganglia, an area of
the brain involved in the regulation of movement. Dopamine turnover has been shown to elevate the levels of ROS in the brain. In addition, a
street-drug contaminant has appeared that can cause parkinsonism in drug abusers. The compound N-methyl-4-phenyl-1, 2, 3,
6tetrahydropyridine (“MPTP”) has been identified in underground laboratory preparations of a potent analog of meperidine (Demerol).
MPTP-containing powder, sometimes sold as a new “synthetic heroin,” can be dissolved in water and administered intravenously or taken by
the intranasal route. MPTP has been documented to produce irreversible chronic Parkinson symptoms in drug abusers. Agents such as MPTP
overproduce ROS in the basal ganglia. Therefore, ROS mediated neuronal dysfunction may play a key role in the development of Parkinson’s
disease. Symptoms of this disease include tremors, rigidity and bradykinesia (i.e., slowness of movement).In the more advanced stages, it can
cause fluctuations in motor function, sleep problems and various neuro-psychiatric disorders. A biological hallmark of Parkinson’s disease is a
reduction in brain dopamine levels. Preventing or slowing the destruction of brain cells that lead to the depletion of dopamine levels in the
brain is an important therapeutic approach for the treatment of this disease.

Pre-clinical studies

     Data developed by our scientists and Dr. Manisha Patel at the University of Colorado Health Sciences Center and Department of Medicine,
indicate that when administered orally, AEOL 11207 is greater than 80% bioavailable, meaning that it is readily absorbed and reaches both the
circulatory system and the brain in sufficient amounts to demonstrate biological activity. Data developed with AEOL 11207 in a widely used
animal model of Parkinson’s disease (the “MPTP model”) showed that when administered orally, AEOL 11207 crosses the blood brain barrier
and protected dopamine neurons in a dose-dependent manner. Further data suggest that the compound has a half- life (a measurement of the
time period for which a compound stays in the body) of about 3 days in both the circulatory system and the brain, and that prior to stopping
administration of the compound, the levels of AEOL 11207 in both the circulatory system and brain reach a steady state (a valuable
measurement of when the levels of the drug in the body remain substantially constant, neither increasing nor decreasing) after 2 days of dosing.
Data have also been developed that indicate that when dosing of AEOL 11207 is stopped, the compound is excreted from the body.


                                                                      65
     In September 2010, Manisha Patel of the University of Colorado was informed by the Michael J. Fox Foundation that she had been
awarded a supplement to her grant. The funds are for the synthesis of additional quantities of AEOL1114B and AEOL11203; for the
completion of the evaluation of AEOL1114B and AEOL11203’s effects on MPTP toxicity (TH+ cells in substantia nigra), and behavioral
testing and accumulation of manganese after chronic dosing.

    Prior to receiving the funding for this program, we filed a new composition of matter and use patent for AEOL 11114B and 11203.

Future Development Plans

     For this and other reasons, we believe that the therapeutic rationale for developing AEOL 11207 as a neuroprotectant, may afford new
therapeutic treatment options for Parkinson’s disease if AEOL 11207 were to achieve regulatory approval for commercialization. However, we
are unable to determine at this time that such regulatory approval for AEOL 11207 can be or will be secured and we will not be able to further
develop AEOL 11207 unless funding for this purpose is obtained.

     AEOL 11207 is patent-protected and has the same chemical core structure as AEOL 10150.Because of this common structural feature, it is
anticipated that AEOL 11207 will evidence substantially the same safety profile in clinical evaluations as observed with AEOL 10150, making
clinical trial design and testing of AEOL 11207 more robust and facile. Furthermore, all of our compounds evidence the ability to scavenge and
decrease ROS and reactive nitrogen species (RNS), all of which are implicated in a variety of CNS diseases.

Funding Options

     The University of Colorado, our research provider for the development of AEOL 11207 for the treatment of Parkinson’s Disease, received
a grant for funding from the Michael J. Fox Foundation to further test AEOL 11207 and several of our other compounds.

    In October 2010, we were notified that we had been awarded the maximum amount, of $244,000, under the QTDP administered by the
IRS and the HHS in support of our development of AEOL 11207 for Parkinson’s Disease. In November 2010, we received approximately
$92,000 from the IRS as an initial payment for the Parkinson’s program award. The balance of about $152,000 would be paid after we file our
2010 fiscal year tax return if we spend approximately $303,000 on the Parkinson’s program during the fiscal year. We did not spend the
required amounts to collect on the remaining $152,000 of the award.

Background on Antioxidants

Oxygen Stress and Disease

     Oxygen plays a pivotal role in supporting life by enabling energy stored in food to be converted to energy that living organisms can use.
The ability of oxygen to participate in key metabolic processes derives from its highly reactive nature. This reactivity is necessary for life, but
also generates different forms of oxygen that can react harmfully with living organisms. In the body, a small proportion of the oxygen we
consume is converted to superoxide, a free radical species that gives rise to hydrogen peroxide, hydroxyl radical, peroxynitrite and various
other oxidants.

     Oxygen-derived free radicals can damage DNA, proteins and lipids resulting in inflammation and both acute and delayed cell death. The
body protects itself from the harmful effects of free radicals and other oxidants through multiple antioxidant enzyme systems such as SOD.
These natural antioxidants convert the reactive molecules into compounds suitable for normal metabolism. When too many free radicals are
produced for the body’s normal defenses to convert, “oxidative stress” occurs with a cumulative result of reduced cellular function and,
ultimately, disease.


                                                                         66
     Data also suggests that oxygen-derived free radicals are an important factor in the pathogenesis of a large variety of diseases, including
neurological disorders such as ALS, Parkinson’s disease, Alzheimer’s disease and stroke, and in non-neurological disorders such as cancer
radiation therapy damage, emphysema, asthma and diabetes.

Antioxidants as Therapeutics

     Because of the role that oxygen-derived free radicals play in disease, scientists are actively exploring the possible role of antioxidants as a
treatment for related diseases. Preclinical and clinical studies involving treatment with SOD, the body’s natural antioxidant enzyme, or more
recently, studies involving over-expression of SOD in transgenic animals, have shown promise of therapeutic benefit in a broad range of
disease therapies. Increased SOD function improves outcome in animal models of conditions including stroke, ischemia-reperfusion injury (a
temporary cutoff of blood supply to tissue) to various organs, harmful effects of radiation and chemotherapy for the treatment of cancer, and in
neurological and pulmonary diseases. Clinical studies with bovine SOD, under the brand Orgotein, or recombinant human SOD in several
conditions including arthritis and protection from limiting side effects of cancer radiation or chemotherapy treatment, have also shown promise
of benefit. The major limitations of enzymatic SOD as a therapeutic are those found with many proteins, most importantly limited cell
penetration and allergic reactions. Allergic reactions led to the withdrawal of Orgotein from almost every worldwide market.

Catalytic Antioxidants vs. Antioxidant Scavengers

     From a functional perspective, antioxidant therapeutics can be divided into two broad categories, scavengers and catalysts. Antioxidant
scavengers are compounds where one antioxidant molecule combines with one reactive oxygen molecule and both are consumed in the
reaction. There is a one-to-one ratio of the antioxidant and the reactive molecule. With catalytic antioxidants, in contrast, the antioxidant
molecule can repeatedly inactivate reactive oxygen molecules, which could result in multiple reactive oxygen molecules combining with each
antioxidant molecule.

     Vitamin derivatives that are antioxidants are scavengers. The SOD enzymes produced by the body are catalytic antioxidants. Catalytic
antioxidants are typically much more potent than antioxidant scavengers, in some instances by a multiple of up to 10,000.

     Use of antioxidant scavengers, such as thiols or vitamin derivatives, has shown promise of benefit in preclinical and clinical studies.
Ethyol, a thiol-containing antioxidant, is approved for reducing radiation and chemotherapy toxicity during cancer treatment, and clinical
studies have suggested benefit of other antioxidants in kidney and neurodegenerative diseases. However, large sustained doses of the
compounds are required as each antioxidant scavenger molecule is consumed by its reaction with the free radical. Toxicities and the
inefficiency of scavengers have limited the utility of antioxidant scavengers to very specific circumstances.

Contracts and Grants

    We seek to advance development of our drug candidates through external funding arrangements. We may slow down development
programs or place them on hold during periods that are not covered by external funding. We have received external funding awards for the
development of AEOL 10150 as an MCM for Lung-ARS, GI-ARS, mustard gas and chlorine gas exposure from the NIH.

BARDA Contract

    For additional information regarding the BARDA Contract, please see “Management’s Discussion and Analysis of Financial Condition
and Results of Operations - BARDA Contract” beginning on page 30 of this prospectus..

BARDA Proposals for the Development of AEOL 10150 as an MCM for Exposure to Chlorine and Sulfur Mustard Gases

     On May 31, 2010, we submitted white papers to BARDA for the development of AEOL 10150 as a MCM for exposure to chlorine gas and
sulfur mustard gas.


                                                                         67
    On September 15, 2010, BARDA informed us that it had accepted our white paper for chlorine gas exposure and requested a full proposal
from the Company. BARDA also informed us that it had not accepted the white paper for sulfur mustard gas.

    On December 10, 2010, we submitted a full proposal to BARDA for the development of AEOL 10150 as a medical countermeasure for
chlorine gas exposure. The proposal sought funding to take the compound from its current state to FDA approval over a three year period. On
June 28, 2011, BARDA informed us that it would not be entering into negotiation with us for the development of the chlorine indication at this
time, but invited us to resubmit our proposal after completion of some of the safety and efficacy studies in our current Lung-ARS program
funded by BARDA. BARDA indicated in its response that there was some overlap in the development program proposed and the current
BARDA Contract, and that it was already funding the radiation indication, which is a very similar program.

NIH and HHS Grants

    AEOL 10150 continues to be the subject of research sponsored by NIH-CounterACT as an MCM for chlorine gas and sulfur mustard gas
exposure at NJH.

    In October 2010, we were notified that we had been awarded the maximum amount, of $244,000, under the QTDP administered by the
IRS and the HHS in support of our development of AEOL 10150 as an MCM for Lung-ARS.

    In October 2010, we were notified that we had been awarded the maximum amount, of $244,000, under the QTDP administered by the
IRS and the HHS in support of our development of AEOL 11207 for Parkinson’s Disease. In November 2010, we received approximately
$92,000 from the IRS as an initial payment for the Parkinson’s program award. The balance of about $152,000 would be paid after we file our
2010 fiscal year tax return if we spend approximately $303,000 on the Parkinson’s program during the fiscal year. We did not spend the
required amounts to collect on the remaining $152,000 of the award.

    We, and our development partners, continue to actively pursue additional government or foundation sponsored development contracts and
grants and to encourage both governmental, non-governmental agencies and philanthropic organizations to provide development funding or to
conduct clinical studies of our drug candidates.

Collaborative and Licensing Arrangements

Duke Licenses

     Pursuant to our license agreements with Duke, we have obtained exclusive worldwide rights from Duke to products using antioxidant
technology and compounds developed by Dr. Irwin Fridovich and other scientists at Duke. We are obligated under the licenses to pay Duke
royalties ranging in the low single digits of net product sales during the term of the Duke licenses, and we must make payments upon the
occurrence of certain development milestones in an aggregate amount of up to $2,000,000. In addition, we are obligated under the Duke
licenses to pay patent filing, prosecution, maintenance and defense costs. The Duke licenses are terminable by Duke in the event of breach by
us and otherwise expire when the last licensed patent expires.

National Jewish Medical and Research Center and National Jewish Health

     We have obtained an exclusive worldwide license from the National Jewish Medical and Research Center (“NJMRC”) to develop, make,
use and sell products using proprietary information and technology developed under a previous Sponsored Research Agreement within the field
of antioxidant compounds and related discoveries. We must make milestone payments to the NJMRC in an aggregate amount of up to
$250,000 upon the occurrence of certain development milestones. Our royalty payment obligations to the NJMRC under this license agreement
are in the low single digits of net product sales. We are also obligated to pay patent filing, prosecution, maintenance and defense costs. This
NJMRC license agreement is terminable by the NJMRC in the event of breach and otherwise expires when the last licensed patent expires.

     In 2009, we obtained an additional exclusive worldwide license from NJH to develop, make, use and sell products using proprietary
information and technology developed at NJH related to certain compounds as an MCM against mustard gas exposure. Under this license
agreement, we must make milestone payments to NJH in an aggregate amount of up to $500,000 upon the occurrence of certain development
milestones. In addition, we must make royalty payments to NJH under this license agreement ranging in the low-single digits as a percentage of
all sublicensing fees, milestone payments and sublicense royalties that we receive from sublicenses granted by us pursuant to this license
agreement. We are also obligated to pay patent filing, prosecution, maintenance and defense costs. This NJH license agreement is terminable
by NJH in the event of breach and otherwise expires when the last licensed patent expires.


                                                                      68
Research and Development Expenditures

    Expenditures for research and development activities were $5,055,000, $1,690,000 and $711,000 during the years ended September 30,
2011, 2010 and 2009, respectively. Research and development expenses for fiscal 2011 related primarily to the advancement of our lead
compound, AEOL 10150.

Manufacturing

     We currently do not have the capability to manufacture any of our drug candidates on a commercial scale. Materials for non-clinical and
clinical studies are produced under contract with third parties. To date, we have partnered with Johnson Matthey for the manufacture of our
active pharmaceutical ingredients. Johnson Matthey is an almost 200 year old company that is a global supplier of active pharmaceutical
ingredients, fine chemicals and other specialty chemical products and services to a wide range of chemical and pharmaceutical industry
customers and industrial and academic research organizations. Johnson Matthey is a leader in the manufacture of metal-based pharmaceutical
products.

Commercialization

     If BARDA elects to procure AEOL10150 pursuant to an EUA, as described above, or after FDA approval, it is possible for the Company
to generate significant sales revenue without the need of raising significant funds to build a commercial organization. Depending on the size of
those procurements, and assuming the successful development and FDA approval of our compounds in other, non-biodefense indications, we
may have sufficient financial resources to internally fund the building of a commercial organization. However, in the event procurements from
BARDA are not made, and assuming successful development and FDA approval of one or more of our compounds, to successfully
commercialize our catalytic antioxidant programs, we must seek corporate partners with expertise in commercialization or develop this
expertise internally. However, we may not be able to successfully commercialize our catalytic antioxidant technology, either internally or
through collaboration with others.

Marketing

     Our potential catalytic antioxidant products are being developed for large therapeutic markets. We believe these markets are best
approached by partnering with established biotechnology or pharmaceutical companies that have broad sales and marketing capabilities. We
are pursuing collaborations of this type as part of our search for development partners. However, we may not be able to enter into any
marketing arrangements for any of our products on satisfactory terms or at all.

Biodefense Industry

Market Overview

     The market for biodefense countermeasures has grown dramatically as a result of the increased awareness of the threat of global terror
activity in the wake of the September 11, 2001 terrorist attacks. The U.S. government is the principal source of worldwide biodefense spending.
Most U.S. government spending on biodefense programs is in the form of development funding from NIAID, BARDA and the Department of
Defense (“DoD”) and procurements of countermeasures by BARDA, the CDC and the DoD. The U.S. government is now the largest source of
development and procurement funding for academic institutions and biotechnology companies conducting biodefense research or developing
vaccines and immunotherapies directed at potential agents of bioterror or biowarfare.

    We analyze the biodefense market in three segments; the United States military market, United States commercial market and non U.S.
markets, with the U.S. government funding representing the vast majority of the worldwide market. According to the Center for Biosecurity at
the University of Pittsburgh Medical Center the U.S. government’s biodefense military and civilian spending approximated $8 billion in fiscal
2009 and has averaged around $5.5 billion from fiscal years 2001 to 2009.Biodefense military and civilian spending in fiscal year 2010 was
expected to be about $6 billion.



                                                                      69
             ● U.S. Civilian : The U.S. civilian market includes funds to protect the U.S. population from biological agents and is largely
                  funded by the Project BioShield Act of 2004 (“Project BioShield”). Project BioShield is the U.S. government’s largest
                  biodefense initiative. It governs and funds with, $5.6 billion, procurements of biodefense countermeasures for the SNS for
                  the period from July 2004 through 2013.
             ● U.S. Military : The DoD is responsible for the development and procurements of countermeasures for the military segment
                  which focuses on providing protection for military personnel and civilians who are on active duty.
             ● Non-U.S. Markets : Non-U.S. markets address protection against biowarfare agents for both civilians and military personnel
                  in foreign countries. We anticipate that foreign countries will want to procure biodefense products as they are developed and
                  validated by procurements by the U.S. government.

 Project BioShield and the Pandemic and All-Hazards Preparedness Act

     Project BioShield became law in 2004 and authorizes procurements of countermeasures for chemical, biological, radiological and nuclear
attacks for the SNS, which is a national repository of medical assets and countermeasures designed to provide federal, state and local public
health agencies with medical supplies needed to treat those affected by terrorist attacks, natural disasters, industrial accidents and other public
health emergencies. Project BioShield provided appropriations of $5.6 billion to be expended over ten years into a special reserve fund.

    The Pandemic and All-Hazards Preparedness Act, passed in 2006, established BARDA as the agency responsible for awarding
procurement contracts for biomedical countermeasures and providing development funding for advanced research and development in the
biodefense arena, and supplements the funding available under Project BioShield for chemical, biological, radiological and nuclear
countermeasures, and provides funding for infectious disease pandemics. Funding for BARDA is provided by annual appropriations by
Congress. Congress also appropriates annual funding for the CDC for procurements of medical assets and countermeasures for the SNS and for
NIAID to conduct biodefense research. This appropriation funding supplements amounts available under Project BioShield.

    Currently, the U.S. government may, at its discretion, purchase critical biodefense products for the SNS prior to FDA approval based on
Emergency Use Authorization enabled under the Project BioShield legislation. On an ongoing basis we monitor notices for requests for
proposal, grants and other potential sources of government funding that could potentially support the development of our drug candidates.
Nevertheless, changes in government budgets, priorities and agendas as well as political pressures could result in a reduction in overall
government financial support for the biodefense sector in general and/or specifically the drug candidates we are developing. Due to the current
economic downturn, the accompanying fall in tax revenues and the U.S. government’s efforts to stabilize the economy, the U.S. government
may be forced or choose to reduce or delay spending in the biodefense field, which could decrease the likelihood of future government contract
awards, the likelihood that the government will exercise its right to extend any of its existing contracts and/or the likelihood that the
government would procure products from us.(For further information, see “Risk Factors — Risks Related to Our Dependence on U.S.
Government Grants and Contracts — Most of our immediately foreseeable future revenues are contingent upon grants and contracts from the
U.S. government and we may not achieve sufficient, if any, revenues from these agreements to attain profitability.”) As a result, further
development of our drug candidates and ultimate product sales to the government, if any, could be delayed or stopped altogether.

Competition

General

     Competition in the pharmaceutical industry is intense and we expect it to increase. Technological developments in our field of research and
development occur at a rapid rate and we expect competition to intensify as advances in this field are made. We will be required to continue to
devote substantial resources and efforts to research and development activities. Our most significant competitors, among others, are fully
integrated pharmaceutical companies and more established biotechnology companies, which have substantially greater financial, technical,
sales, marketing and human resources than we do. These companies may succeed in developing and obtaining regulatory approval for
competitive products more rapidly than we can for our drug candidates. In addition, competitors may develop technologies and products that
are, or are perceived as being, cheaper, safer or more effective than those being developed by us or that would render our technology obsolete.

     We expect that important competitive factors in our potential product markets will be the relative speed with which we and other
companies can develop products, complete the clinical testing and approval processes, and supply commercial quantities of a competitive
product to the market. With respect to clinical testing, competition might result in a scarcity of clinical investigators and patients available to
test our potential products, which could delay development.


                                                                         70
    We are aware of products in research or development by our competitors that address the diseases and therapies being targeted by us. In
addition, there may be other competitors of whom we are unaware with products which might be more effective or have fewer side effects than
our products and those of our known competitors.

Antioxidants

     Several companies have explored the therapeutic potential of antioxidant compounds in numerous indications. Historically, most of these
companies have focused on engineered versions of naturally occurring antioxidant enzymes, but with limited success, perhaps because the large
size of these molecules makes delivery into the cells difficult. Antioxidant drug research continues at a rapid pace despite previous clinical
setbacks.

Patents and Proprietary Rights

     We currently license rights to our potential products from third parties. We generally seek patent protection in the United States and other
jurisdictions for the potential products and proprietary technology licensed from these third parties. The process for preparing and prosecuting
patents is lengthy, uncertain and costly. Patents may not issue on any of the pending patent applications owned by us or licensed by us from
third parties. Even if patents issue, the claims allowed might not be sufficiently broad to protect our technology or provide us protection against
competitive products or otherwise be commercially valuable. Patents issued to or licensed by us could be challenged, invalidated, infringed,
circumvented or held unenforceable. Even if we successfully defend our patents for our products, the costs of defense can be significant.

     As of December 1, 2011, our catalytic antioxidant small molecule technology base is described in 12 issued United States patents and four
United States pending patent applications. These patents and patent applications belong in whole or in part to Duke or the NJH and are licensed
to us. These patents and patent applications cover soluble manganese porphyrins as antioxidant molecules as well as targeted compounds
obtained by coupling such antioxidant compounds to molecules that bind to specific extracellular elements. The pending U.S. patent
applications and issued U.S. patents include composition of matter claims and method claims for several series of compounds. Corresponding
international patent applications have been filed, 83 of which have issued, and one of which has been allowed as of December 1, 2011. Our 12
issued U.S. patents will expire between 2015 and 2023.

     In addition to patent protection, we rely upon trade secrets, proprietary know-how and technological advances that we seek to protect, in
part, through confidentiality agreements with our collaborative partners, employees and consultants. Our employees and consultants are
required to enter into agreements providing for confidentiality and the assignment of rights to inventions made by them while in our service.
We also enter into non-disclosure agreements to protect our confidential information furnished to third parties for research and other purposes.

Government Regulation

     Our research and development activities and the manufacturing and marketing of our future products are subject to regulation by numerous
governmental agencies in the United States and in other countries. The FDA and comparable agencies in other countries impose mandatory
procedures and standards for the conduct of clinical trials and the production and marketing of products for diagnostic and human therapeutic
use. Before obtaining regulatory approvals for the commercial sale of any of our products under development, we must demonstrate through
preclinical studies and clinical trials that the product is safe and efficacious for use in each target indication. The results from preclinical studies
and early clinical trials might not be predictive of results that will be obtained in large-scale testing. Our clinical trials might not successfully
demonstrate the safety and efficacy of any products or result in marketable products.

     The United States system of drug approvals is considered to be the most rigorous in the world. It takes an average of 8.5 years for a drug
candidate to move through the clinical and approval phases in the United States according to a November 2005 study by the Tufts Center for
the Study of Drug Development. Only five in 5,000 drug candidates that enter preclinical testing make it to human testing and only one of those
five is approved for commercialization. On average, it costs a company $897 million to get one new drug candidate from the laboratory to
United States patients according to a May 2003 report by Tufts Center for the Study of Drug Development. A November 2006 study by Tufts
Center for the Study of Drug Development reported that the average cost of developing a new biotechnology product was $1.2 billion and took
on average slightly more than eight years to be approved by the FDA.


                                                                          71
    The steps required by the FDA before new drug products may be marketed in the United States include:

             ● completion of preclinical studies;
             ● the submission to the FDA of a request for authorization to conduct clinical trials on an IND, which must become effective
                  before clinical trials may commence;
             ● adequate and well-controlled Phase I clinical trials which typically involves normal, healthy volunteers. The tests study a
                  drug candidate’s safety profile, including the safe dosage range. The studies also determine how a drug is absorbed,
                  distributed, metabolized and excreted as well as the duration of its action;
             ● adequate and well-controlled Phase II clinical trials which typically involve treating patients with the targeted disease with
                  the drug candidate to assess a drug’s effectiveness;
             ● adequate and well-controlled Phase III clinical trials involving a larger population of patients with the targeted disease are
                  treated with the drug candidate to confirm efficacy of the drug candidate in the treatment of the targeted indication and to
                  identify adverse events;
             ● submission to the FDA of an NDA; and
             ● review and approval of the NDA by the FDA before the product may be shipped or sold commercially.

     In addition to obtaining FDA approval for each product, each product manufacturing establishment must be registered with the FDA and
undergo an inspection prior to the approval of an NDA. Each manufacturing facility and its quality control and manufacturing procedures must
also conform and adhere at all times to the FDA’s cGMP regulations. In addition to preapproval inspections, the FDA and other government
agencies regularly inspect manufacturing facilities for compliance with these requirements. Manufacturers must expend substantial time,
money and effort in the area of production and quality control to ensure full technical compliance with these standards.

     Preclinical testing includes laboratory evaluation and characterization of the safety and efficacy of a drug and its formulation. Preclinical
testing results are submitted to the FDA as a part of an IND which must become effective prior to commencement of clinical trials. Clinical
trials are typically conducted in three sequential phases following submission of an IND. Phase I represents the initial administration of the
drug to a small group of humans, either patients or healthy volunteers, typically to test for safety (adverse effects), dosage tolerance, absorption,
distribution, metabolism, excretion and clinical pharmacology, and, if possible, to gain early evidence of effectiveness. Phase II involves
studies in a small sample of the actual intended patient population to assess the efficacy of the drug for a specific indication, to determine dose
tolerance and the optimal dose range and to gather additional information relating to safety and potential adverse effects. Once an
investigational drug is found to have some efficacy and an acceptable safety profile in the targeted patient population, Phase III studies are
initiated to further establish clinical safety and efficacy of the therapy in a broader sample of the general patient population, in order to
determine the overall risk-benefit ratio of the drug and to provide an adequate basis for any physician labeling. During all clinical studies, we
must adhere to good clinical practices (“GCPs”) standards. The results of the research and product development, manufacturing, preclinical
studies, clinical studies and related information are submitted in an NDA to the FDA.

     The process of completing clinical testing and obtaining FDA approval for a new drug is likely to take a number of years and require the
expenditure of substantial resources. If an application is submitted, there can be no assurance that the FDA will review and approve the NDA.
Even after initial FDA approval has been obtained, further studies, including post-market studies, might be required to provide additional data
on safety and will be required to gain approval for the use of a product as a treatment for clinical indications other than those for which the
product was initially tested and approved. Also, the FDA will require post-market reporting and might require surveillance programs to monitor
the side effects of the drug. Results of post-marketing programs might limit or expand the further marketing of the products. Further, if there
are any modifications to the drug, including changes in indication, manufacturing process, labeling or a change in manufacturing facility, an
NDA supplement might be required to be submitted to the FDA.

      The rate of completion of any clinical trials will be dependent upon, among other factors, the rate of patient enrollment. Patient enrollment
is a function of many factors, including the size of the patient population, the nature of the trial, the availability of alternative therapies and
drugs, the proximity of patients to clinical sites and the eligibility criteria for the study. Delays in planned patient enrollment might result in
increased costs and delays, which could have a material adverse effect on us.


                                                                         72
     Failure to comply with applicable FDA requirements may result in a number of consequences that could materially and adversely affect us.
Failure to adhere to approved trial standards and GCPs in conducting clinical trials could cause the FDA to place a clinical hold on one or more
studies which would delay research and data collection necessary for product approval. Noncompliance with GCPs could also have a negative
impact on the FDA’s evaluation of an NDA. Failure to adhere to GMPs and other applicable requirements could result in FDA enforcement
action and in civil and criminal sanctions, including but not limited to fines, seizure of product, refusal of the FDA to approve product approval
applications, withdrawal of approved applications, and prosecution.

     Whether or not FDA approval has been obtained, approval of a product by regulatory authorities in foreign countries must be obtained
prior to the commencement of marketing of the product in those countries. The requirements governing the conduct of clinical trials and
product approvals vary widely from country to country, and the time required for approval might be longer or shorter than that required for
FDA approval. Although there are some procedures for unified filings for some European countries, in general, each country at this time has its
own procedures and requirements. There can be no assurance that any foreign approvals would be obtained.

    In addition to the regulatory framework for product approvals, we and our collaborative partners must comply with laws and regulations
regarding occupational safety, laboratory practices, the use, handling and disposition of radioactive materials, environmental protection and
hazardous substance control, and other local, state, federal and foreign regulation. The impact of such regulation upon us cannot be predicted
and could be material and adverse.

Legislation and Regulation Related to Bioterrorism Counteragents

    Because some of our drug candidates are intended for the treatment of diseases that may result from acts of bioterrorism, they may be
subject to the specific legislation and regulation described below.

Project BioShield

     Project BioShield provides expedited procedures for bioterrorism related procurements and awarding of research grants, making it easier
for HHS to quickly commit funds to countermeasure projects. Project BioShield relaxes procedures under the Federal Acquisition Regulation
for procuring property or services used in performing, administering or supporting biomedical countermeasure research and development. In
addition, if the Secretary of HHS deems that there is a pressing need, Project BioShield authorizes the Secretary to use an expedited award
process, rather than the normal peer review process, for grants, contracts and cooperative agreements related to biomedical countermeasure
research and development activity.

Under Project BioShield, the Secretary of HHS, with the concurrence of the Secretary of the Department of Homeland Security (“DHS”), and
upon the approval of the President, can contract to purchase unapproved countermeasures for the SNS in specified circumstances. Congress is
notified of a recommendation for a stockpile purchase after Presidential approval. Project BioShield specifies that a company supplying the
countermeasure to the SNS is paid on delivery of a substantial portion of the countermeasure. To be eligible for purchase under these
provisions, the Secretary of HHS must determine that there are sufficient and satisfactory clinical results or research data, including data, if
available, from preclinical and clinical trials, to support a reasonable conclusion that the countermeasure will qualify for approval or licensing
within eight years. Project BioShield also allows the Secretary of HHS to authorize the emergency use of medical products that have not yet
been approved by the FDA. To exercise this authority, the Secretary of HHS must conclude that:

             ● the agent for which the countermeasure is designed can cause serious or life-threatening disease;
             ● the product may reasonably be believed to be effective in detecting, diagnosing, treating or preventing the disease;
             ● the known and potential benefits of the product outweigh its known and potential risks; and
             ● there is no adequate alternative to the product that is approved and available.

     Although this provision permits the Secretary of HHS to circumvent the FDA approval process, its use would be limited to rare
circumstances.


                                                                        73
Safety Act

     The Support Anti-Terrorism by Fostering Effective Technologies Act enacted by the U.S. Congress in 2002 (the “Safety Act”) creates
product liability limitations for qualifying anti-terrorism technologies for claims arising from or related to an act of terrorism. In addition, the
Safety Act provides a process by which an anti-terrorism technology may be certified as an “approved product” by the DHS and therefore
entitled to a rebuttable presumption that the government contractor defense applies to sales of the product. The government contractor defense,
under specified circumstances, extends the sovereign immunity of the United States to government contractors who manufacture a product for
the government. Specifically, for the government contractor defense to apply, the government must approve reasonably precise specifications,
the product must conform to those specifications and the supplier must warn the government about known dangers arising from the use of the
product.

Public Readiness and Emergency Preparedness Act

    The Public Readiness and Emergency Preparedness Act enacted by Congress in 2005 (the “PREP Act”) provides immunity for
manufacturers from all claims under state or federal law for “loss” arising out of the administration or use of a “covered countermeasure”.
However, injured persons may still bring a suit for “willful misconduct” against the manufacturer under some circumstances. “Covered
countermeasures” include security countermeasures and “qualified pandemic or epidemic products”. For these immunities to apply, the
Secretary of HHS must issue a declaration in cases of public health emergency or “credible risk” of a future public health emergency. We
cannot predict whether Congress will fund the relevant PREP Act compensation programs; or whether the necessary prerequisites for immunity
would be triggered with respect to our drug candidates.

Foreign Regulation

     In addition to regulations in the United States, we will be subject to a variety of foreign regulations governing clinical trials and
commercial sales and distribution of our products. Whether or not we obtain FDA approval for a product, we must obtain approval of a product
by the comparable regulatory authorities of foreign countries before we can commence clinical trials or marketing of the product in those
countries. The actual time required to obtain clearance to market a product in a particular foreign jurisdiction may vary substantially, based
upon the type, complexity and novelty of the pharmaceutical product candidate and the specific requirements of that jurisdiction. The
requirements governing the conduct of clinical trials, marketing authorization, pricing and reimbursement vary from country to country.

Reimbursement and Pricing Controls

    In many of the markets where we could commercialize a drug candidate following regulatory approval, the prices of pharmaceutical
products are subject to direct price controls by law and to reimbursement programs with varying price control mechanisms.

     In the United States, there is an increasing focus on drug pricing in recent years. There are currently no direct government price controls
over private sector purchases in the United States. However, the Veterans Health Care Act establishes mandatory price discounts for certain
federal purchasers, including the Veterans Administration, Department of Defense and the Public Health Service; the discounts are based on
prices charged to other customers.

    Under the Medicaid program (a joint federal/state program that provides medical coverage to certain low income families and individuals),
pharmaceutical manufacturers must pay prescribed rebates on specified drugs to enable them to be eligible for reimbursement. Medicare (the
federal program that provides medical coverage for the elderly and disabled) generally reimburses for physician-administered drugs and
biologics on the basis of the product’s average sales price. Outpatient drugs may be reimbursed under Medicare Part D. Part D is administered
through private entities that attempt to negotiate price concessions from pharmaceutical manufacturers. Various states have adopted further
mechanisms that seek to control drug prices, including by disfavoring higher priced products and by seeking supplemental rebates from
manufacturers. Managed care has also become a potent force in the marketplace and increases downward pressure on the prices of
pharmaceutical products.

     Public and private health care payors control costs and influence drug pricing through a variety of mechanisms, including through
negotiating discounts with the manufacturers and through the use of tiered formularies and other mechanisms that provide preferential access to
particular products over others within a therapeutic class. Payors also set other criteria to govern the uses of a drug that will be deemed
medically appropriate and therefore reimbursed or otherwise covered. In particular, many public and private health care payors limit
reimbursement and coverage to the uses that are either approved by the FDA or that are supported by other appropriate evidence, such as
published medical literature, and appear in a recognized compendium. Drug compendia are publications that summarize the available medical
evidence for particular drug products and identify which uses are supported or not supported by the available evidence, whether or not such
uses have been approved by the FDA.


                                                                         74
     Different pricing and reimbursement schemes exist in other countries. In the European Union, governments influence the price of
pharmaceutical products through their pricing and reimbursement rules and control of national health care systems that fund a large part of the
cost of those products to consumers. Some jurisdictions operate positive and negative list systems under which products may only be marketed
once a reimbursement price has been agreed. Other member states allow companies to fix their own prices for medicines, but monitor and
control company profits. The downward pressure on health care costs in general, particularly prescription drugs, has become very intense. As a
result, increasingly high barriers are being erected to the entry of new products. In addition, in some countries cross-border imports from
low-priced markets exert a commercial pressure on pricing within that country.

Regulations Regarding Government Contracting

     We may become a government contractor in the United States and elsewhere which would mean that we would be subject to various
statutes and regulations that govern procurements of goods and services by agencies of the United States and other countries, including the
Federal Acquisition Regulation. These governing statutes and regulations can impose stricter penalties than those normally applicable to
commercial contracts, such as criminal and civil damages liability and suspension and debarment from future government contracting. In
addition, pursuant to various statutes and regulations, our government contracts may be subject to unilateral termination or modification by the
government for convenience in the United States and elsewhere, detailed auditing requirements and accounting systems, statutorily controlled
pricing, sourcing and subcontracting restrictions and statutorily mandated processes for adjudicating contract disputes.

Hazardous Materials and Select Agents

    Our development and manufacturing processes involve the use of hazardous materials, including chemicals and radioactive materials, and
produce waste products. Accordingly, we are subject to federal, state and local laws and regulations governing the use, manufacturing, storage,
handling and disposal of these materials. In addition to complying with environmental and occupational health and safety laws, we must
comply with special regulations relating to biosafety administered by the CDC, HHS and the DoD.

 Other Regulations

     In the United States and elsewhere, the research, manufacturing, distribution, sale and promotion of drug and biological products are
subject to regulation by various federal, state and local authorities in addition to the FDA, including the Centers for Medicare and Medicaid
Services; other divisions of HHS, such as the Office of Inspector General: the U.S. Department of Justice and individual U.S. Attorney offices
within the Department of Justice and state and local governments. For example, sales, marketing and scientific and educational grant programs
must comply with the anti-kickback and fraud and abuse provisions of the Social Security Act, the False Claims Act, the privacy provisions of
the Health Insurance Portability and Accountability Act and similar state laws. Pricing and rebate programs must comply with the Medicaid
rebate requirements of the Omnibus Budget Reconciliation Act of 1990 and the Veterans Health Care Act of 1992.All of these activities are
also potentially subject to federal and state consumer protection and unfair competition laws.

CPEC, LLC

     We were previously developing bucindolol for the treatment of heart failure, but development was discontinued in 1999.Commercial rights
to bucindolol are owned by CPEC, LLC, a limited liability company (“CPEC”), of which we own 35% and Endo Pharmaceuticals (formerly
Indevus Pharmaceuticals), Inc. owns 65%.

     During fiscal 2008, CPEC received a milestone payment from ARCA of $500,000.The milestone payment was triggered by the acceptance
by the FDA of an NDA for bucindolol. Future milestone payments and royalty payments to us and CPEC, if any, while provided for under the
agreement between CPEC and ARCA, cannot be assured or guaranteed. Also as a result of the filing of the NDA with the FDA, we were
obligated to pay $413,000 in the form of cash or stock at our election to the majority owner of CPEC who in turn paid the original licensors of
bucindolol per the terms of the 1994 Purchase Agreement of CPEC. On November 6, 2009, we issued 1,099,649 shares of common stock to the
majority owner of CPEC to satisfy our obligation.

    During fiscal 2009, we sold our holdings of ARCA, generating a gain of $133,000. In addition, during fiscal 2009, ARCA received a
Complete Response letter from the FDA for its NDA for bucindolol for the treatment of patients with chronic heart failure. In the Complete
Response letter, the FDA stated that it cannot approve the NDA in its current form and specifies additional actions and information required for
approval of the bucindolol NDA.


                                                                       75
Employees

    At May 10, 2012, we had six full-time employees. None of our employees is represented by a labor union. In addition to our employees,
we utilize several consultants to perform key functions for the Company.




                                                                    76

companies. Mr. Rallis’ experiences in development activities and strategic alliances are valuable to Board deliberations. In addition, his venture
capital consulting experience allows him to contribute additional insight to the Board in refining our Company’s business strategies and
commercial objectives.

         No stock options were exercised by any Named Executive Officer during the fiscal year ended September 30, 2011.

Employment Agreement with John McManus

          On July 30, 2010, we and John McManus entered into an amended and restated employment agreement (the “Restated Agreement”).
Under the Restated Agreement, Mr. McManus serves as President, Chief Executive Officer and Chief Operating Officer of the Company.
Pursuant to the Restated Agreement, Mr. McManus is paid $20,850 per month. However, in the event, on or prior to June 30, 2011, we
(i) entered into one or more binding agreements for the sale and issuance of our equity in one or more financings, (ii) entered into one or more
binding partnership, licensing, collaboration, development or similar agreements, or (iii) were awarded one or more grants or contracts, all of
which taken together collectively entitle us to receive gross proceeds of at least $10,000,000 (the “Threshold Amount”) (excluding any
proceeds received from the Investors or any affiliate thereof), Mr. McManus’ salary would be increased to $33,333 per month, effective as of
the date of such agreement or award, when combined with all prior agreements or awards, entitles us to the Threshold Amount. Mr. McManus’
salary was increased to $33,333 per month effective February 11, 2011 upon receipt of the contract with the BARDA.

          Under the Restated Agreement, we will also continue to grant Mr. McManus on an annual basis a stock option to purchase 250,000
shares of the common stock with an exercise price equal to the closing price of the common stock, as reported on the OTC Bulletin Board, on
the day of the grant. The options will vest at a rate of 20,833 shares per month from the grant date for twelve months, provided that
Mr. McManus is an employee or consultant of us on the applicable vesting date. In the event of a sale of the Company, through a merger or
otherwise, all of the options held by Mr. McManus shall be fully vested and immediately exercisable. In addition, the Restated Agreement
provides that Mr. McManus will be entitled to receive a cash bonus of not less than $100,000 if during the term of the Restated Agreement we
enter into a definitive agreement for a development or partnership with another life sciences company for the joint development or
commercialization of any of our owned or in-licensed patent rights or for a change of control of the Company, including through an acquisition
or merger.


                                                                       84
          The initial term of the Restated Agreement was through June 30, 2011, and the current term is through June 30, 2012 unless
terminated earlier. The Restated Agreement will automatically renew for additional one-year periods unless either party gives written notice at
least 90 days prior to the commencement of the next 1-year term of the agreement, of such party’s intent not to renew the agreement. If the
Restated Agreement is terminated by us for any reason other than for cause, we shall pay Mr. McManus all payments due and owing, if any,
under the agreement as if the agreement continued in effect for the full remainder of the current term.

Letter Agreement and Consulting Agreement with Russell Skibsted

          On September 1, 2010, we and Russell Skibsted entered into an offer letter agreement, pursuant to which we offered Mr. Skibsted
full-time employment as our Senior Vice President, Chief Financial Officer and Secretary commencing upon the announcement of a contract
for the development of AEOL 10150 as a medical countermeasure with BARDA. On February 15, 2011, we announced a contract with
BARDA for the development of AEOL 10150 (the “BARDA Contract”) and concurrently appointed Mr. Skibsted to the position of Senior
Vice President, Chief Financial Officer and Secretary in accordance with the terms of the Offer Letter. The Offer Letter provides that
Mr. Skibsted will be entitled to a monthly salary of $20,833.33 and that Mr. Skibsted will be entitled to participate in all of our current
customary employee benefit plans and programs, subject to eligibility requirements, enrollment criteria and the other terms and conditions of
such plans and programs. In addition, pursuant to the Offer Letter, Mr. Skibsted was granted a stock option to purchase 360,000 shares of the
common stock under the 2004 Plan. The stock option has an exercise price of $0.60 per share, the closing stock price of our common stock on
the date of grant, and vests at a rate of 30,000 shares per month over a period of twelve months from the date of grant.

        For the period from September 1, 2010 through immediately prior to our announcement of the BARDA Contract, Mr. Skibsted had
been providing consulting services to us pursuant to a Consulting Agreement, dated as of September 1, 2010, between us and Mr. Skibsted (the
“Skibsted Consulting Agreement”). Pursuant to the Skibsted Consulting Agreement, Mr. Skibsted received a monthly consulting fee of
$15,000 per month. The Skibsted Consulting Agreement was terminated on February 15, 2011 concurrent with our appointment of
Mr. Skibsted as our Senior Vice President, Chief Financial Officer and Secretary pursuant to the Offer Letter.

Consulting Arrangements

         Until June 30, 2011, McManus & Company, Inc. (“M&C”), which is owned by Mr. John McManus, provided us with administrative,
accounting and financial consulting services. In addition, M&C also provided us with our corporate headquarters, facilities management and
the outsourcing of the administrative, accounting, finance and accounting functions. Pursuant to an agreement with M&C, we paid M&C a
monthly consulting payment of $25,000. In addition, the agreement provided for a cash bonus of $20,000 upon the declaration of the
effectiveness of each Registration Statement on Form S-1, S-3 or S-4 with the SEC; a cash payment of $15,000 upon the filing of a Preliminary
Proxy Statement with the SEC except for the Proxy Statement related to our annual stockholder meeting; and a cash payment of $50,000 upon
a change of control such that another entity acquires and/or merges with Aeolus. During fiscal 2010 and 2011, we paid M&C $320,000 and
$180,000, respectively, in consulting fees pursuant to services rendered by M&C under the agreement.

          On December 1, 2010, we and our wholly-owned subsidiary, Aeolus Sciences, Inc., entered into a Consulting Agreement (the
“Consulting Agreement”) with Dr. Brian J. Day, our Chief Scientific Officer. Pursuant to the Consulting Agreement, Dr. Day will be entitled to
receive a monthly consulting fee of $11,500 and may also be granted cash bonuses for his contributions to us. Dr. Day’s monthly consulting fee
will increase to $12,500 when and if, during the term of the Consulting Agreement, we obtain at least $5,000,000 in funding through either a
capital raising transaction, partnership or contract award. In addition, Dr. Day will be granted a stock option to purchase 50,000 shares of our
common stock with an exercise price equal to the closing stock price on the date of grant. The option will vest at a rate of 4,167 shares per
month as long as Dr. Day continues to be a consultant to, or an employee of, the Company, except in the case of a Sale of the Companies (as
defined below), in which case the option shall fully vest and be immediately exercisable. For purposes of the Consulting Agreement, a “Sale of
the Company” is defined as a merger, business combination, reorganization, recapitalization or other transaction which results in the
stockholders of the Company who own at least 50% of the Company’s voting control immediately prior to such transaction owning less than
50% of the surviving entity’s voting control immediately after such transaction, and/or a sale, transfer, lease or other disposition in any
transaction or series of transactions of all or substantially all of the assets of the Company.

           Pursuant to the Consulting Agreement, Dr. Day will also be entitled to receive a cash bonus of $30,000 and will be granted a stock
option to purchase an additional 25,000 shares of the common stock with an exercise price equal to the closing stock price on the date of grant
when and if, during the term of the Consulting Agreement: (1) we execute definitive agreements representing the earliest to occur of: (a) a
development or partnership with another life sciences company for the joint development or commercialization of any of our owned or
in-licensed patent rights, or (b) a Sale of the Company; or (2) we file an Investigational New Drug application for a new compound in our drug
candidate pipeline with the U.S. Food and Drug Administration. All options granted pursuant to the foregoing sentence shall vest on the date
that is six months from the date of grant as long as Dr. Day continues to be a consultant to, or an employee of, the Company, except in the case
of a Sale of the Company, in which case the option shall fully vest and be immediately exercisable.


                                                                       85
       The term of the Consulting Agreement commenced on December 1, 2010 and will continue for an initial term of one year expiring on
November 30, 2011, which may be extended upon mutual agreement of the parties. The Company has extended the agreement upon mutual
agreement and is currently working to execute a new contract for another year.

 (3)    Percent of shares beneficially owned by any person is calculated by dividing the number of shares of preferred stock beneficially
owned by that person by 577,073, the number of shares of preferred stock outstanding as of the close of business on May 10, 2012, and the

currently exercisable or may be exercised within 60 days after May 10, 2012 as well as shares of preferred stock convertible into common

for computing the ownership percentage of the person holding such options but are not deemed to be outstanding for computing the ownership
percentage of any other person.

         Under our Amended and Restated Certificate of Incorporation, our board of directors has the authority to issue preferred stock in one
or more series and to fix the rights, preferences, privileges and restrictions, including the dividend, conversion, voting, redemption (including
sinking fund provisions), and other rights, liquidation preferences, and the number of shares constituting any series and the designations of such
series, without any further vote or action by our stockholders.

           Because the terms of the preferred stock may be fixed by our board of directors without stockholder action, the preferred stock could
be issued quickly with terms calculated to defeat a proposed takeover of our company or to make the removal of our management more
difficult. Under certain circumstances this could have the effect of decreasing the market price of our common stock.

         Series B Convertible Preferred Stock

         All shares of Series B Convertible Preferred Stock and warrants to purchase shares of Series B Convertible Preferred Stock currently
are owned by Elan Corporation plc. The Series B Convertible Preferred Stock is non-voting stock. Each share of Series B Convertible Preferred
Stock is convertible into one shares of our common stock, provided that no conversion may be effected that would result in the holders of
Series B Convertible Preferred Stock owning more than 9.9% of our common stock on a fully converted to common stock basis. If we pay a
cash dividend on our common stock, we also must pay the same dividend on an as converted basis on the Series B Convertible Preferred Stock.

        Section 203 of the Delaware Corporation Law

         Section 203 of the General Corporation Law of the State of Delaware (the “DGCL”) prevents an “interested stockholder” (defined in
Section 203 of the DGCL, generally, as a person owning 15% or more of a corporation’s outstanding voting stock), from engaging in a
“business combination” (as defined in Section 203 of the DGCL) with a publicly-held Delaware corporation for three years following the date
such person became an interested stockholder, unless:

            ● before such person became an interested stockholder, the board of directors of the corporation approved the transaction in
                 which the interested stockholder became an interested stockholder or approved the business combination;

            ● upon consummation of the transaction that resulted in the interested stockholder’s becoming an interested stockholder, the
                 interested stockholder owns at least 85% of the voting stock of the corporation outstanding at the time the transaction
                 commenced (excluding stock held by directors who are also officers of the corporation and by employee stock plans that do
                 not provide employees with the rights to determine confidentially whether shares held subject to the plan will be tendered in
                 a tender or exchange offer); or

            ● following the transaction in which such person became an interested stockholder, the business combination is approved by
                 the board of directors of the corporation and authorized at a meeting of stockholders by the affirmative vote of the holders of
                 two-thirds of the outstanding voting stock of the corporation not owned by the interested stockholder.


                                                                      96
 Our certificate of incorporation expressly provides that the provisions of Section 203 of the DGCL do not apply. Consequently, a person or
entity wishing to acquire control of our company would not have to comply with the director or stockholder approvals required by Section 203.
This could make a takeover of our company easier even if the takeover were not approved by the board of directors or opposed by the
stockholders as not being in their best interests.

         Limitation of Liability

         Section 145 of the DGCL provides a detailed statutory framework covering indemnification of officers and directors against liabilities
and expenses arising out of legal proceedings brought against them by reason of their being or having been directors or officers. Section 145
generally provides that a director or officer of a corporation:

             ● shall be indemnified by the corporation for all expenses of such legal proceedings when he is successful on the merits;

             ● may be indemnified by the corporation for the expenses, judgments, fines and amounts paid in settlement of such
                  proceedings (other than a derivative suit), even if he is not successful on the merits, if he acted in good faith and in a manner
                  he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal
                  action or proceeding, had no reasonable cause to believe his conduct was unlawful; and

             ● may be indemnified by the corporation for the expenses of a derivative suit (a suit by a stockholder alleging a breach by a
                  director or officer of a duty owed to the corporation), even if he is not successful on the merits, if he acted in good faith and
                  in a manner he reasonably believed to be in or not opposed to the best interests of the corporation.

 The indemnification discussed in clauses two and three above may be made only upon a determination that indemnification is proper because
the applicable standard of conduct has been met. Such a determination may be made by a majority of a quorum of disinterested directors,
independent legal counsel, the stockholders or a court of competent jurisdiction. The indemnification discussed in clause three above may not
apply, however, if the director or officer is adjudged liable for negligence or misconduct in the performance of his duties to the corporation,
unless a corporation determines that despite such adjudication, but in view of all the circumstances, he is entitled to indemnification.

           Article Sixth of our certificate of incorporation provides in substance that, to the fullest extent permitted by the DGCL as it now exists
or as amended, each director and officer shall be indemnified against reasonable costs and expenses, including attorney’s fees, and any
liabilities which he may incur in connection with any action to which he may be made a party by reason of his being or having been a director
or officer of our company. The indemnification provided by our certificate of incorporation is not deemed exclusive of or intended in any way
to limit any other rights to which any person seeking indemnification may be entitled. Section 102(b)(7) of the DGCL permits a corporation to
provide in its certificate of incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders for
monetary damages for breach of fiduciary duty as a director, except for liability

             ● for any breach of the director’s duty of loyalty to the corporation or its stockholders,

             ● for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law,

             ● under Section 174 of the DGCL, or

             ● for any transaction from which the director derived an improper personal benefit.

          Article Eighth of our certificate of incorporation provides for the elimination of personal liability of a director for breach of fiduciary
duty, as permitted by Section 102(b)(7) of the DGCL. We maintain liability insurance on our officers and directors against liabilities that they
may incur in such capacities. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or
persons controlling our company pursuant to the foregoing provisions, we have been informed that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.


                                                                          97
         Anti-Takeover Effects

         Bylaws

         Our Bylaws are designed to make it difficult for a third party to acquire control of us, even if a change of control would be beneficial
to stockholders. Our Bylaws do not permit any person other than the board of directors or certain executive officers to call special meetings of
the stockholders. In addition, we must receive a stockholders’ proposal for an annual meeting within a specified period for that proposal to be
included on the agenda. Because stockholders do not have the power to call meetings and are subject to timing requirements in submitting
stockholder proposals for consideration at an annual or special meeting, any third-party takeover not supported by the board of directors would
be subject to significant delays and difficulties.

         No Cumulative Voting

          The DGCL provides that stockholders are denied the right to cumulate votes in the election of directors unless our amended and
restated certificate of incorporation provides otherwise. Our amended and restated certificate of incorporation does not provide for cumulative
voting.

         Undesignated Preferred Stock

          The authority that is possessed by our Board of Directors to issue preferred stock could potentially be used to discourage attempts by
third parties to obtain control of our company through a merger, tender offer, proxy contest or otherwise by making such attempts more
difficult or more costly. Our Board of Directors may issue preferred stock with voting rights or conversion rights that, if exercised, could
adversely affect the voting power of the holders of common stock.

         Authorized but Unissued Shares

         Our authorized but unissued shares of common stock and preferred stock will be available for future issuance without stockholder
approval. We may use additional shares for a variety of purposes, including future offerings to raise additional capital, to fund acquisitions and
as employee compensation. The existence of authorized but unissued shares of common stock and preferred stock could render more difficult
or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

          The combination of the provisions summarized above will make it more difficult for our stockholders to replace our Board of
Directors as well as for another party to obtain control of us by replacing our Board of Directors. Therefore, these provisions may have the
effect of deterring hostile takeovers or delaying changes in our control or management. These provisions are intended to enhance the likelihood
of continued stability in the composition of our Board of Directors and in the policies they implement, and to discourage certain types of
transactions that may involve an actual or threatened change of our control. These provisions are designed to reduce our vulnerability to an
unsolicited acquisition proposal. The provisions also are intended to discourage certain tactics that may be used in proxy fights. However, such
provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they also may inhibit
fluctuations in the market price of our shares that could result from actual or rumored takeover attempts. Such provisions may also have the
effect of preventing changes in our management.

         Xmark Warrants

    Among other restrictions, the Xmark Warrants prohibit the sale of our company to an entity other than one that is publicly traded.


         Transfer Agent and Registrar

         The transfer agent and registrar for our common stock is American Stock Transfer and Trust Company.


                                                                        98
                                                           PLAN OF DISTRIBUTION

          The selling stockholders, which as used herein includes donees, pledgees, transferees or other successors-in-interest selling shares of
common stock or interests in shares of common stock received after the date of this prospectus from a selling stockholder as a gift, pledge,
partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of common
stock or interests in shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private
transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market
price, at varying prices determined at the time of sale, or at negotiated prices.

         The selling stockholders may use any one or more of the following methods when disposing of shares or interests therein:

         - ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

         - block trades in which the broker-dealer will attempt to sell the shares as agent, but may position and resell a portion of the block as
principal to facilitate the transaction;

         - purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

         - an exchange distribution in accordance with the rules of the applicable exchange;

         - privately negotiated transactions;

       - short sales effected after the date the registration statement of which this Prospectus is a part is declared effective by the
Commission;

         - through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

         - broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share;

         - a combination of any such methods of sale; and

         - any other method permitted by applicable law.

          The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of common stock
owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares
of common stock, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable
provision of the Securities Act amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as
selling stockholders under this prospectus. The selling stockholders also may transfer the shares of common stock in other circumstances, in
which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

          In connection with the sale of our common stock or interests therein, the selling stockholders may enter into hedging transactions with
broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the
positions they assume. The selling stockholders may also sell shares of our common stock short and deliver these securities to close out their
short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling stockholders may also
enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities
which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such
broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

         The aggregate proceeds to the selling stockholders from the sale of the common stock offered by them will be the purchase price of
the common stock less discounts or commissions, if any. Each of the selling stockholders reserves the right to accept and, together with their
agents from time to time, to reject, in whole or in part, any proposed purchase of common stock to be made directly or through agents. We will
not receive any of the proceeds from this offering. Upon any exercise of the warrants by payment of cash, however, we will receive the
exercise price of the warrants.


                                                                         99
         The selling stockholders also may resell all or a portion of the shares in open market transactions in reliance upon Rule 144 under the
Securities Act of 1933, provided that they meet the criteria and conform to the requirements of that rule.

         The selling stockholders and any underwriters, broker-dealers or agents that participate in the sale of the common stock or interests
therein may be "underwriters" within the meaning of Section 2(11) of the Securities Act. Any discounts, commissions, concessions or profit
they earn on any resale of the shares may be underwriting discounts and commissions under the Securities Act. Selling stockholders who are
"underwriters" within the meaning of Section 2(11) of the Securities Act will be subject to the prospectus delivery requirements of the
Securities Act.

         Each selling stockholder has advised us that they have not entered into any written or oral agreements, understandings or arrangements
with any underwriter or broker-dealer regarding the sale of the resale shares. There is no underwriter or coordinating broker acting in
connection with the proposed sale of the resale shares by the selling stockholders.

         To the extent required, the shares of our common stock to be sold, the names of the selling stockholders, the respective purchase
prices and public offering prices, the names of any agents, dealer or underwriter, any applicable commissions or discounts with respect to a
particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration
statement that includes this prospectus.

         In order to comply with the securities laws of some states, if applicable, the common stock may be sold in these jurisdictions only
through registered or licensed brokers or dealers. In addition, in some states the common stock may not be sold unless it has been registered or
qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

         We have advised the selling stockholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales
of shares in the market and to the activities of the selling stockholders and their affiliates. In addition, to the extent applicable we will make
copies of this prospectus (as it may be supplemented or amended from time to time) available to the selling stockholders for the purpose of
satisfying the prospectus delivery requirements of the Securities Act. The selling stockholders may indemnify any broker-dealer that
participates in transactions involving the sale of the shares against certain liabilities, including liabilities arising under the Securities Act.

          We have agreed to indemnify the selling stockholders against certain liabilities, including liabilities under the Securities Act and state
securities laws, relating to the registration of the shares offered by this prospectus.

          We have agreed with the selling stockholders to keep the registration statement of which this prospectus constitutes a part effective
until the earlier of (1) such time as all of the shares covered by this prospectus have been disposed of pursuant to and in accordance with the
registration statement or (2) the date on which the shares may be sold without volume restrictions pursuant to Rule 144 of the Securities Act.


                                                                        100

     A. Organization, Business and Summary of Significant Accounting Policies

    Organization

    The accompanying unaudited condensed consolidated financial statements include the accounts of Aeolus Pharmaceuticals, Inc. and its
wholly-owned subsidiary, Aeolus Sciences, Inc. (collectively, “we,” “us,” “the Company” or “Aeolus”). All significant intercompany accounts
and transactions have been eliminated in consolidation. Aeolus is a Delaware corporation. The Company’s primary operations are located in
Mission Viejo, California.

    Business

     Aeolus Pharmaceuticals, Inc. is a biopharmaceutical company that is developing a platform of a new class of broad-spectrum, catalytic
antioxidant compounds based on technology discovered at Duke University and National Jewish Health. The Company’s lead compound,
AEOL 10150, is a metalloporphyrin specifically designed to neutralize reactive oxygen and nitrogen species. The Company is developing
AEOL 10150 as a medical countermeasure against the pulmonary effects of radiation exposure under theBARDA Contract valued at up to
$118.4 million with the BARDA, a division of the Department of Health and Human Services (“HHS”). The Company is also developing it for
use in oncology indications where it would be used in combination with radiation and chemotherapy. Additionally, Aeolus receives
development support from the National Institutes of Health (“NIH”) for development of the compound as a medical countermeasure against
radiation and chemical exposure.

    Basis of Presentation

     The condensed consolidated financial statements of Aeolus included herein have been prepared by management, without audit (except for
the Consolidated Balance Sheet as of September 30, 2011), pursuant to the rules and regulations of the Securities and Exchange Commission
(“SEC”). Certain information normally included in the condensed consolidated financial statements prepared in accordance with accounting
principles generally accepted in the United States has been condensed or omitted pursuant to such rules and regulations. However, the
Company believes that the disclosures are adequate to make the information presented not misleading. The Company recommends that you
read the condensed consolidated financial statements included herein in conjunction with the audited consolidated financial statements and
notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2011, filed with the SEC on
December 27, 2011.

     All significant intercompany activity has been eliminated in the preparation of the condensed consolidated financial statements. In the
opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments (consisting only of
normal recurring adjustments) necessary to present fairly the consolidated financial position, results of operations and cash flows of the
Company. The condensed balance sheet at September 30, 2011 was derived from the Company’s audited financial statements included in the
Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2011, filed with the SEC on December 27, 2011. The
unaudited condensed consolidated financial statements included herein should be read in conjunction with the audited consolidated financial
statements and the notes thereto included in that Annual Report on Form 10-K and in the Company’s other SEC filings. Results for the interim
period are not necessarily indicative of the results for any other period.

    Reclassifications

    Certain immaterial prior quarter amounts have been reclassified to conform to the current year presentation.

    Use of Estimates

     The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent
assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.



                                                                     F-4
    Cash and Cash Equivalents

    The Company invests available cash in short-term bank deposits. Cash and cash equivalents include investments with maturities of three
months or less at the date of purchase. The carrying value of cash and cash equivalents approximate their fair market value at March 31, 2012
and 2011 due to their short-term nature.

    Significant customer and accounts receivable

    For the six months ended March 31, 2012 and 2011, the Company’s primary customer was BARDA. For the six months ended March 31,
2012 and 2011, revenues from BARDA comprised 100% of total revenues. As of March 31, 2012, the Company’s receivable balances were
comprised 100% from this customer. Unbilled accounts receivable, included in accounts receivable, totaling $917,000 and $205,000 as of
March 31, 2012 and September 30, 2011, respectively, relate to work that has been performed, though invoicing has not yet occurred. All of the
unbilled receivables are expected to be billed and collected within the next 12 months. Accounts receivable are stated at invoice amounts and
consist primarily of amounts due from BARDA. If necessary, the Company records a provision for doubtful receivables to allow for any
amounts which may be unrecoverable. This provision is based upon an analysis of the Company’s prior collection experience, customer
creditworthiness and current economic trends. As of March 31, 2012 and September 30, 2011, an allowance for doubtful accounts was not
recorded as the collection history from the Company’s customers indicated that collection was probable.

    Concentrations of credit risk

     Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents
and accounts receivable. The Company places its cash and cash equivalents with high quality financial institutions. Management believes that
the financial risks associated with its cash and cash equivalents and investments are minimal. Because accounts receivable consist primarily of
amounts due from the U.S. federal government agencies, management deems there to be minimal credit risk.

    Revenue Recognition

     Aeolus recognizes revenue in accordance with the authoritative guidance for revenue recognition. Revenue is recognized when all of the
following criteria are met: (i) persuasive evidence of an arrangement exists, (ii) delivery (or passage of title) has occurred or services have been
rendered, (iii) the seller’s price to the buyer is fixed or determinable, and (iv) collectability is reasonably assured.

     The BARDA Contract is classified as a “cost-plus-fixed-fee” contract. Aeolus recognizes government contract revenue in accordance with
the authoritative guidance for revenue recognition including the authoritative guidance specific to federal government contracts. Reimbursable
costs under the contract primarily include direct labor, subcontract costs, materials, equipment, travel, and indirect costs. In addition, we
receive a fixed fee under the BARDA Contract, which is unconditionally earned as allowable costs are incurred and is not contingent on
success factors. Reimbursable costs under the BARDA Contract, including the fixed fee, are recognized as revenue in the period the
reimbursable costs are incurred and become billable.

    Fair Value of Financial Instruments

    The carrying amounts of our short-term financial instruments, which include cash and cash equivalents, accounts receivable, accounts
payable, and accrued liabilities approximate their fair values due to their short maturities.

    Fair Value Measurements

    The Company follows Accounting Standards Codification (“ASC”) Topic 820, Fair Value Measurements and Disclosures, for financial
and non-financial assets and liabilities.

     ASC Topic 820 discusses valuation techniques, such as the market approach (comparable market prices), the income approach (present
value of future income or cash flow) and the cost approach (cost to replace the service capacity of an asset or replacement cost). The statement
utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following
is a brief description of those three levels:

        ● Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities.
        ● Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include
             quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in
             markets that are not active.
        ● Level 3: Unobservable inputs that reflect the reporting entity’s own assumptions.


                                                                        F-5
The warrant liability is measured at fair market value on a recurring basis as of March 31, 2012 and September 31, 2011 and is summarized
below (in thousands):

                          Fair value at March 31, 2012                            Fair value at September 30, 2011
                     Level 1           Level 2              Level 3           Level 1              Level 2             Level 3

The following table summarizes as of March 31, 2012 the warrant activity subject to Level 3 inputs which are measured on a recurring basis:

B.       Liquidity

    The Company had cash and cash equivalents of $390,000 on March 31, 2012, and $1,186,000 on December 31, 2011. The decrease in
cash was primarily due to cash used in operations. The Company had accounts receivable of $2,479,000 on March 31, 2012, and $1,677,000
on September 30, 2011, and Accounts payable of $3,376,000 on March 31, 2012, and $2,144,000 on September 30, 2011.

     The Company had net income of $2,763,000 (including a non-cash adjustment for decreases in valuation of warrants of $3,324,000) and a
net income of $5,740,000 (including a non-cash charge for increases in valuation of warrants of $7,012,000) for the three and six months ended
March 31, 2012, respectively. For the same periods, the Company had cash outflows from operations of $1,181,000 and cash inflows from
operations of $513,000. The Company expects to incur additional losses and negative cash flow from operations during the remainder of fiscal
year 2012 and for potentially several more years.

     The BARDA Contract’s value could be up to $118.4 million depending on options exercised by BARDA and the requirements for
approval by the U.S. Food and Drug Administration. Under the BARDA Contract, substantially all of the costs of the development of AEOL
10150 as a medical countermeasure for pulmonary injuries resulting from an acute exposure to radiation from a radiological/nuclear accident or
attack, particularly injuries associated with acute radiation syndrome (“ARS”) or Delayed Effects of Acute Radiation Exposure would be paid
for by the U.S. government. The Company recognized $2,231,000 and $4,446,000 in revenue during the three and six months ended March 31,
2012 related to the BARDA Contract. On April 16, 2012, the Company announced that BARDA had exercised two contract options worth
approximately $9.1M. The bulk of the options are for the period of performance beginning April 1, 2012 and ending March 31, 2013.

     The pulmonary sub-syndrome of ARS program supported by the advanced research and development contract with BARDA is fully
funded. Since the terms of the BARDA Contract include provisions to cover some general corporate overhead as well as a small provision for
profit, the net impact of the contract on the Company’s liquidity is that its projected cash burn has been reduced, but not eliminated. Certain
costs, typically those of being a public company, like legal costs associated with being a public company, IR/PR costs and patent-related costs,
are not included in overhead reimbursement in the BARDA Contract.

     The Company has incurred significant losses since its inception. At March 31, 2012, the Company’s accumulated deficit was
$176,672,000. This raises substantial doubt about our ability to continue as a going concern, which will be dependent on our ability to generate
sufficient cash flows to meet the Company’s obligations on a timely basis, obtain additional financing and, ultimately, achieve operating profits
through product sales or BARDA procurements. The Company intends to explore strategic and financial alternatives, which may include a
merger or acquisition with or by another company, the sale of shares of stock and/or convertible debentures, the establishment of new
collaborations for current research programs that include initial cash payments and on-going research support and the out-licensing of our
compounds for development by a third party. The Company believes that without additional investment capital it will not have sufficient cash
to fund its activities in the near future, and will not be able to continue operating. As such, the Company’s continuation as a going concern is
dependent upon its ability to raise additional financing. If the Company is unable to obtain additional financing to fund operations, it will need
to eliminate some or all of its activities, merge with another company, sell some or all of its assets to another company, or cease operations
entirely. There can be no assurance that the Company will be able to obtain additional financing on acceptable terms or at all, or that the
Company will be able to merge with another Company or sell any or all of its assets.


                                                                        F-6
C.       Warrant Liability

     Increases or decreases in fair value of the warrants are included as a component of other income (expenses) in the accompanying statement
of operations for the respective period. As of March 31, 2012, the aggregate liability for warrants decreased to $16,393,000, resulting in a gain
to the statements of operations for the three and six months ended March 31, 2012 of $3,324,000 and $7,012,000, respectively. The warrant
liability and revaluations have not and will not have any impact on the Company’s working capital, liquidity or business operations due to the
non-cash nature of the liability.

D.       Note Payable

Elan Note Payable

     In August 2002, Aeolus borrowed $638,000 from Elan Corporation, plc (“Elan”) pursuant to a promissory note. The note payable accrued
interest at 10% compounded semi-annually. The note was convertible at the option of Elan into shares of the Company’s Series B non-voting
convertible preferred stock (“Series B Stock”) at a rate of $43.27 per share. The original note matured on December 21, 2006. However, in
February 2007, the Company and Elan terminated the note, the Company paid $300,000 in cash to Elan and Elan forgave $225,000 of the note
payable. Elan and the Company entered into a new two-year note payable in the amount of $453,000 under substantially the same terms as the
original note. In February 2009, the Company and Elan agreed to amend the new note payable to extend its maturity date from February 7,
2009 to February 7, 2011 and increased the interest rate of the convertible promissory note from 10% to 11% effective February 7, 2009. As of
the date of the amendment, an aggregate of $553,000 in principal and interest was outstanding under the convertible promissory note. In the
event of a default under the terms of the convertible promissory note, Elan had the right to demand immediate payment of all amounts
outstanding under the note. For purposes of the note, an event of default included, among other items, a default in the payment of the note
principal or interest when due and payable, an uncured breach by the Company of its obligations to Elan pursuant the agreements under which
the convertible promissory note was issued, an inability of the Company to pay its debts in the normal course of business, the cessation of
business activities by the Company (other than as a result of a merger or consolidation with a third party) without Elan’s prior written consent
and the appointment of a liquidator, receiver, administrator, examiner, trustee or similar officer of the Company or over all or substantially all
of its assets under the law.

     During the term of the note payable, Elan had the option to convert the note into shares of Series B Stock at a rate of $9.00 per share. Upon
the maturity of the note payable, Aeolus had the option to repay the note either in cash or in shares of Series B Stock and warrants having a
then fair market value equal to the amount due under the note; provided that the fair market value used for calculating the number of shares to
be issued would not be less than $13.00 per share.

     On February 7, 2011, the maturity date of the note, Aeolus elected to exercise its right to repay the note, with a maturity value of $663,000,
by issuing 50,993 shares of Series B Stock and a warrant to purchase an aggregate of 896,037 shares of Series B Stock at an exercise price of
$0.01 per share. The warrant has a term of five years, a cashless exercise provision and customary anti-dilution adjustments in the event of
stock splits, stock combination, reorganizations and similar events. In connection with the issuance, Aeolus amended its certificate of
incorporation on February 7, 2011 to increase the authorized number of shares of Series B Stock from 600,000 to 1,600,000. The fair value of
the warrants issued on February 7, 2011 was estimated to be $452,000 using the Black-Scholes option pricing model with the following
assumptions: dividend yield of 0%, expected volatility of 93.3%, risk free interest rate of 2.39% and an expected life of five years.

E.       Stockholders’ Equity

Preferred Stock

    The Certificate of Incorporation of Aeolus authorizes the issuance of up to 10,000,000 shares of Preferred Stock, at a par value of $.01 per
share. The Board of Directors has the authority to issue Preferred Stock in one or more series, to fix the designation and number of shares of
each such series, and to determine or change the designation, relative rights, preferences, and limitations of any series of Preferred Stock,
without any further vote or action by the stockholders of the Company.

     Of the 10,000,000 shares of total authorized shares of Preferred Stock, 1,250,000 shares are designated as Series A Convertible Preferred
Stock and 1,600,000 shares are designated as Series B Stock. The Series B Stock is not entitled to vote on any matter submitted to the vote of
holders of the common stock except that the Company must obtain the approval of a majority of the outstanding shares of Series B Stock to
either amend the Company’s Certificate of Incorporation in a manner that would adversely affect the Series B Stock (including by creating an
additional class or series of stock with rights that are senior or pari passu to the Series B Stock) or change the rights of the holders of the Series
B Stock in any other respect. Each share of Series B Stock is convertible at any time by the holder thereof into one share of the Company’s
common stock, provided that no conversion may be effected that would result in the holders of Series B Stock owning more than 9.9% of the
Company’s common stock on a fully converted to common stock basis. If the Company pays a cash dividend on its common stock, it must also
pay the same dividend on an as converted basis on the Series B Stock. Upon a liquidation, dissolution, bankruptcy or winding up of the
Company or the sale of all or substantially all of the Company’s assets, the holders of Series B Stock will be entitled to receive, together with
the holders of common stock, the assets of the Company in proportion to the number of shares of common stock held (assuming conversion of
the Series B Stock into shares of common stock).
F-7
    As of March 31, 2012, no shares of Series A stock were outstanding; 526,080 shares of Series B Stock were outstanding, all of which were
held by Elan. Each share of Series B Stock was convertible into one share of common stock as of March 31, 2012.

    There were no shares of Series A Convertible Preferred Stock issued or outstanding as of March 31, 2012.

Common Stock

March 2012 Financing

     On March 30, 2012 and April 4, 2012, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with
certain accredited investors (the “Purchasers”). Under the terms of the agreement, the Company received $660,000 in gross proceeds in
exchange for the issuance of an aggregate of approximately 2,200,166 units (the “Units”) at a purchase price of $0.30 per unit. Each Unit
consists of (i) one share of common stock (the “Common Shares”) and (ii) a five year warrant to purchase 0.75 of a share of the Company’s
common stock (the “Warrants”). The Warrants have an initial exercise price of $0.40 per share.

    On March 30, 2012, the Company received $530,000 in gross proceeds in exchange for the issuance of an aggregate of 1,766,833 Units,
which consisted of 1,766,833 shares of common stock and 1,325,126 warrants.

    On April 4, 2012, the Company received $130,000 in gross proceeds in exchange for the issuance of an aggregate of approximately
433,333 Units, which consisted of 433,333 shares of common stock and 325,000 warrants.

     Net cash proceeds from the March 2012 Financing, after deducting for expenses, were $645,000. The Company also incurred non-cash
expenses in the form of 12,501 warrants issued to consultants, at similar terms as the financing Warrants, for services provided. The Company
issued a total of $1,337,627 warrants as of March 30, 2012 in connection with the March 2012 Financing.

     The fair value of the March 2012 Financing warrants was estimated to be $363,000 using the Black-Scholes option pricing model with the
following assumptions: dividend yield of 0%, expected volatility of 150.74%, risk free interest rate of 1.04% and an expected life of five years.
The proceeds from the March 2012 Financing were allocated based upon the relative fair values of the March 2012 Financing Warrants and the
March 2012 Common Shares.

     The March 2012 Financing contains a registration rights agreement with an arrangement for liquidated damages in the event of a failure to
file with the SEC a registration statement covering the March 2012 Financing Units. The Company has 45 days after the closing date, March
30, 2012 and April 4, 2012, to file the registration statement. In the event the registration statement is not timely filed, the Company will be
required to make a cash payment of 0.5% of the aggregate amount invested to the Purchasers of the March 2012 Financing Units. The 0.5%
payment equaling $3,300 would be due after each 30 day period following the closing date for a maximum of 6 months. The maximum liability
would be $18,150. As of March 30, 2012, no liability was recorded as the Company expects to timely file the registration statement.

August 2010 Financing

     On August 12, 2010, the Company announced an additional financing (the “August 2010 Financing”) with certain existing investors (the
“August 2010 Investors”). Under the terms of the agreement, the Company received $1.0 million in gross proceeds in exchange for the issuance
of 2.5 million shares of common stock and warrants to purchase up to 1,875,000 shares at an exercise price of $0.50 per s h are. The Company
also granted to the August 2010 Investors the option to acquire, collectively, up to an additional 2,500,000 units, comprised of an aggregate of
2,500,000 shares of common stock and warrants to purchase up to an aggregate of 1,875,000 additional shares of common stock at an exercise
price of $0.50 (the “August 2010 Call Option”). In addition, the August 2010 Investors granted to the Company the option to require these
August 2010 Investors, severally and not jointly, to acquire up to 2,500,000 additional units, less any additional units acquired under the
August 2010 Call Option, at the per additional unit purchase price of $0.40 (the “August 2010 Put Option”).


                                                                       F-8
    Net cash proceeds from the August 2010 Financing, after deducting for expenses, were $900,000.

     The fair value of the August 2010 Financing warrants was estimated to be $542,000 using the Black-Scholes option pricing model with the
following assumptions: dividend yield of 0%, expected volatility of 91.83%, risk free interest rate of 2.08% and an expected life of seven years.
The proceeds from the August 2010 Financing were allocated based upon the relative fair values of the August 2010 Financing warrants and
the August 2010 Shares. Due to the variable strike price provision of the August 2010 Financing warrants, these warrants were deemed to be a
liability under current accounting guidance and, as a result, the warrant liability was increased by $542,000, of which $179,000 was recorded as
a charge to the Statement of Operations, and $363,000 of proceeds from the August 2010 Financing was allocated to the value of the August
2010 Warrants.

     On December 28, 2010, the investors exercised their Call Option and the Company received $1.0 million in proceeds in exchange for
2,500,000 common shares and 1,875,000 warrants, with an initial exercise price of $0.50 per share, subject to adjustment as provided in the
warrants (the “Additional Warrants”). The Additional Warrants are exercisable for a seven-year period from their date of issuance; contain a
“cashless exercise” feature that allows the holder to exercise the Additional Warrants without a cash payment to the Company under certain
circumstances; contain a dividend participation right which allows the holder to receive any cash dividends paid on the common stock without
exercising the Additional Warrant; contain a provision that provides for the reduction of the exercise price to $0.01 in the event of any such
payment of cash dividends by the Company or upon a change of control; and contain anti-dilution provisions in the event of a stock dividend or
split, dividend payment or other issuance, reorganization, recapitalization or similar event.

    The net proceeds to the Company from the December 2010 financing, after deducting for expenses, were $990,000.

     The fair value of the August 2010 Call Option warrants was estimated to be $912,000 using the Black-Scholes option pricing model with
the following assumptions: dividend yield of 0%, expected volatility of 90.51%, risk free interest rate of 2.89% and an expected life of seven
years. The proceeds from the August 2010 Call Option exercise were allocated based upon the relative fair values of the August 2010 Call
Option warrants and the August 2010 Put Option shares. Due to the variable strike price provision of the August 2010 Call Option warrants,
these warrants were deemed to be a liability under current accounting guidance and as a result the warrant liability was increased by $912,000
of which $534,000 was recorded as a charge to the Statement of Operations and $378,000 of proceeds from the August 2010 Call Option
exercise was allocated to the value of the August 2010 Call Option warrants.

Dividends

     The Company has never paid a cash dividend on its common stock and does not anticipate paying cash dividends on its common stock in
the foreseeable future. If the Company pays a cash dividend on its common stock, it also must pay the same dividend on an as converted basis
on its outstanding Series B Stock. In addition, under the terms of the warrants to purchase up to 59,149,999 shares of the Company’s common
stock issued to Xmark Opportunity Partners, LLC or its affiliates in four transactions (on each of October 6, 2009, July 30, 2010, August 11,
2010 and December 31, 2010), if the Company were to pay a dividend on its common stock, the exercise price of these warrants would be reset
from $0.28 per share or $0.50 per share, as applicable, to $0.01 per share and the warrant holders would also be entitled to receive any such
dividend paid.

     The total unrecognized compensation expense for outstanding and unvested stock options for the six months ended March 31, 2012 was
$139,000. The weighted average remaining recognition period for the total deferred compensation expense is approximately nine months. The
fair value of the options associated with the above compensation expense was determined at the date of the grant using the Black-Scholes
option pricing model with the following weighted average assumptions:

     G. Net Income (Loss) Per Common Share

    The Company computes basic net income (loss) per weighted average share attributable to common stockholders using the weighted
average number of shares of common stock outstanding during the period. The Company computes diluted net income (loss) per weighted
average share attributable to common stockholders using the weighted average number of shares of common and dilutive potential common
shares outstanding during the period. Potential common shares outstanding consist of stock options, warrants and convertible preferred stock
using the treasury stock method and are excluded if their effect is anti-dilutive.

    In the computation of diluted earnings per common share for the three months ended March 31, 2012 and 2011, we have excluded
9,044,155 and 8,488,571 stock options, respectively, with exercise prices greater than the average market price of the underlying common
stock, because their inclusion would have been anti-dilutive. Furthermore, for the three months ended March 31, 2012 and 2011, we have
excluded 52,616,300 and 7,200,000 warrants, respectively, with exercise prices greater than the average market price of the underlying
common stock, because their inclusion would have been anti-dilutive.

     In the computation of diluted earnings per common share for the six months ended March 31, 2012 and 2011, we have excluded 8,879,133
and 8,488,571 stock options, respectively, with exercise prices greater than the average market price of the underlying common stock, because
their inclusion would have been anti-dilutive. Furthermore, for the six months ended March 31, 2012 and 2011, we have excluded 48,295,498
and 68,887,117 warrants, respectively, with exercise prices greater than the average market price of the underlying common stock, because
their inclusion would have been anti-dilutive.

     H. Commitments

     The Company acquires assets still in development and enters into research and development arrangements with third parties that often
require milestone and royalty payments to the third party contingent upon the occurrence of certain future events linked to the success of the
asset in development. Milestone payments may be required, contingent upon the successful achievement of an important point in the
development life-cycle of the pharmaceutical product (e.g., approval of the product for marketing by a regulatory agency). If required by the
arrangement, the Company may have to make royalty payments based upon a percentage of the sales of the pharmaceutical product in the event
that regulatory approval for marketing is obtained. Because of the contingent nature of these payments, they are not included in the table of
contractual obligations. No milestones have been met, nor have any payments been paid, as of March 31, 2012.

     We are also obligated to pay patent filing, prosecution, maintenance and defense costs, if any, for the intellectual property we have
licensed from National Jewish Health, National Jewish Medical and Research Center and Duke University.

     These arrangements may be material individually, and in the unlikely event that milestones for multiple products covered by these
arrangements were reached in the same period, the aggregate charge to expense could be material to the results of operations in any one period.
In addition, these arrangements often give Aeolus the discretion to unilaterally terminate development of the product, which would allow
Aeolus to avoid making the contingent payments; however, Aeolus is unlikely to cease development if the compound successfully achieves
clinical testing objectives.



                                                                       F-12
      I. Subsequent Events

    The Company completed a portion of its March Financing on April 4, 2012 as described in Note F Common Stock above.

     On April 16, 2012, we announced that BARDA had exercised two contract options worth approximately $9.1M. The bulk of the options
are for the period of performance beginning April 1, 2012 and ending March 31, 2013 as described more fully in Item 2 below under “BARDA
Contract”.

    We have evaluated subsequent events through the issuance of these condensed consolidated financial statements and determined that no
other material subsequent events have occurred.




                                                                   F-13
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Shareholders
Aeolus Pharmaceuticals Inc.

We have audited the accompanying consolidated balance sheet of Aeolus Pharmaceuticals Inc. (the “Company”) as of September 30, 2011, and
the related consolidated statements of operations, shareholders’ equity (deficit), and cash flows. These financial statements are the
responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those
standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material
misstatement. The company is not required to have, nor were we engaged to perform an audit of its internal control over financial
reporting. Our audit included consideration of internal control over financials reporting as a basis for designing audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over
financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the
amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as
well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Aeolus
Pharmaceutical Inc. and its subsidiary as of September 30, 2011, and the consolidated results of their operations and their cash flows for the
period ended September 30, 2011, in conformity with accounting principles generally accepted in the United States of America.

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note
C to the financial statements, the Company has an accumulated deficit s of $182,412,000 as of September 30, 2011, and, as of that date, the
Company’s total liabilities exceeded its total assets by $23,259,000 and had cash used in operations of $3,102,000 with a cash balance of
$518,000. These conditions, along with other matters as set forth in Note C, raise substantial doubt about the Company’s ability to continue as
a going concern. Management’s plans in regard to these matters are also described in Note C. The financial statements do not include any
adjustments that might result from the outcome of this uncertainty.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those
standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material
misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial
reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over
financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the
amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as
well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position
of Aeolus Pharmaceuticals, Inc. as of September 30, 2010, and the consolidated results of its operations and its cash flows for each of the years
ended September 30, 2010 and 2009, in conformity with accounting principles generally accepted in the United States of America.

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As
discussed in Note C of the consolidated financial statements, the Company has suffered recurring losses, negative cash flows from operations
and management believes the Company does not currently possess sufficient working capital to fund its operations past the second quarter of
fiscal 2012. These matters raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard
to these matters are also described in Note C. The consolidated financial statements do not include any adjustments that might result from the
outcome of this uncertainty.

                                      NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                                   SEPTEMBER 30, 2011

A. Organization, Business and Summary of Significant Accounting Policies

      Organization

       The accompanying audited consolidated financial statements include the accounts of Aeolus Pharmaceuticals, Inc. and its wholly-owned
subsidiary, Aeolus Sciences, Inc. (collectively “we,” “us,” “Company” or “Aeolus”). All significant intercompany accounts and transactions
have been eliminated in consolidation. Aeolus is a Delaware corporation. The Company’s primary operations are located in Mission Viejo,
California.

      Business

       Aeolus is developing a new class of broad-spectrum, catalytic antioxidant compounds based on technology discovered at Duke
University and National Jewish Health. The Company’s lead compound, AEOL 10150, is a metalloporphyrin specifically designed to
neutralize reactive oxygen and nitrogen species. The Company is developing AEOL 10150 as a medical countermeasure against the pulmonary
effects of radiation exposure under the BARDA Contract valued at up to $118.4 million with the BARDA, a division of the Department of
Health and Human Services (“HHS”). Additionally, Aeolus receives development support from the National Institutes of Health (“NIH”) for
development of the compound as a medical countermeasure against radiation and chemical exposure.

B. Summary of Significant Accounting Policies

      Basis of Presentation

      The consolidated financial statements include the accounts of Aeolus and its wholly owned subsidiary. All significant intercompany
accounts and transactions have been eliminated. The Company uses the equity method to account for its 35.0% ownership interest in CPEC.

      Reclassifications

      Certain immaterial prior year amounts have been reclassified to conform to the current year presentation.

      Use of Estimates

       The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent
assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

      Cash and Cash Equivalents

      The Company invests available cash in short-term bank deposits. Cash and cash equivalents include investments with maturities of three
months or less at the date of purchase. The carrying value of cash and cash equivalents approximate their fair market value at September 30,
2011 and 2010 due to their short-term nature.

      Significant customers and accounts receivable

       For the year ended September 30, 2011, the Company’s primary customer was BARDA. For the year ended September 30, 2011,
revenues from BARDA comprised 100% of total revenues. As of September 30, 2011, the Company’s receivable balances were comprised
100% from this customer. Unbilled accounts receivable, included in accounts receivable, totaling $205,000 as of September 30, 2011 relate to
work that has been performed, though invoicing has not yet occurred. All of the unbilled receivables are expected to be billed and collected
within the next 12 months. Accounts receivable are stated at invoice amounts and consist primarily of amounts due from HHS as well as
amounts due under reimbursement contracts with other government entities and non-government and philanthropic organizations. If necessary,
the Company records a provision for doubtful receivables to allow for any amounts which may be unrecoverable. This provision is based upon
an analysis of the Company’s prior collection experience, customer creditworthiness and current economic trends. As of December 31, 2010
and 2009, an allowance for doubtful accounts was not recorded as the collection history from the Company’s customers indicated that
collection was probable.
F-20
      Concentrations of credit risk

       Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents
and accounts receivable. The Company places its cash and cash equivalents with high quality financial institutions. Management believes that
the financial risks associated with its cash and cash equivalents and investments are minimal. Because accounts receivable consist primarily of
amounts due from the U.S. federal government agencies, management deems there to be minimal credit risk.

      Revenue Recognition

      Aeolus recognizes revenue in accordance with the authoritative guidance for revenue recognition. Revenue is recognized when all of the
following criteria are met: (i) persuasive evidence of an arrangement exists, (ii) delivery (or passage of title) has occurred or services have been
rendered, (iii) the seller’s price to the buyer is fixed or determinable, and (iv) collectability is reasonably assured.

       The BARDA Contract is classified as a “cost-plus-fixed-fee” contract. Aeolus recognizes government contract revenue in accordance
with the authoritative guidance for revenue recognition including the authoritative guidance specific to federal government contracts.
Reimbursable costs under the contract primarily include direct labor, subcontract costs, materials, equipment, travel, and indirect costs. In
addition, we receive a fixed fee under the BARDA Contract, which is unconditionally earned as allowable costs are incurred and is not
contingent on success factors. Reimbursable costs under this BARDA Contract, including the fixed fee, are recognized as revenue in the period
the reimbursable costs are incurred and become billable.

      Fair Value of Financial Instruments

      The carrying amounts of our short-term financial instruments, which include cash and cash equivalents, accounts receivable, accounts
payable, and accrued liabilities approximate their fair values due to their short maturities.

      Fair Value Measurements

      The Company adopted Accounting Standards Codification (“ASC”) Topic 820, Fair Value Measurements and Disclosures, for financial
and non-financial assets and liabilities.

        ASC 820 discusses valuation techniques, such as the market approach (comparable market prices), the income approach (present value
of future income or cash flow) and the cost approach (cost to replace the service capacity of an asset or replacement cost). The Company
utilizes the market approach. The statement utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair
value into three broad levels. The following is a brief description of those three levels:

         ● Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities.

          ● Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include
            quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in
            markets that are not active.

          ● Level 3: Unobservable inputs that reflect the reporting entity’s own assumptions.


                                                                       F-21
 The warrant liability is measured at fair market value on a recurring basis as of September 30, 2011 and September 30, 2010 and is
summarized below (in thousands):

                       Fair value at September 30, 2011                             Fair value at September 30, 2010

                   Level 1             Level 2             Level 3              Level 1            Level 2              Level 3

The following table summarizes, as of September 30, 2011, the warrant activity subject to Level 3 inputs which are measured on a recurring
basis:

Research and Development

      Research and development costs are expensed in the period incurred.

Leases

      The Company leases office space and office equipment under month to month operating lease agreements. For the years ended
September 30, 2011, 2010, and 2009, total rent expense was approximately $18,000, $11,000 and $10,000, respectively.

Income Taxes

        Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and
liabilities using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. Valuation allowances are
established when necessary to reduce net deferred tax assets to the amounts expected to be realized.

Net Income (Loss) Per Common Share

       The Company computes basic net income (loss) per weighted average share attributable to common stockholders using the weighted
average number of shares of common stock outstanding during the period. The Company computes diluted net income (loss) per weighted
average share attributable to common stockholders using the weighted average number of shares of common and dilutive potential common
shares outstanding during the period. Potential common shares outstanding consist of stock options, convertible debt, warrants and convertible
preferred stock using the treasury stock method and are excluded if their effect is anti-dilutive. Diluted weighted average common shares
included incremental shares of approximately 22,828,000 shares for the fiscal year ended September 30, 2011 issuable upon the exercise or
conversion of convertible debt, stock options to purchase common stock, convertible preferred stock and warrants to purchase common stock.
Diluted weighted average common shares included incremental shares issuable upon conversion of the Notes, but excluded incremental shares
of approximately 75,372,000 and 36,954,000 respectively for the fiscal year 2009 and 2008, due to their anti-dilutive effect as a result of the
Company’s net loss for the fiscal year 2010 and 2009.



                                                                         F-22

                                                                                      2011                  2010                 2009

Accounting for Stock-Based Compensation

      The Company recognizes stock based compensation expense in the statement of operations based upon the fair value of the equity award
amortized over the vesting period.

Segment Reporting

      The Company currently operates in one segment.

Warrant Liability

        On October 1, 2009, the Company adopted new accounting guidance originally referred to as Emerging Issues Task Force 07-5, recently
codified as Accounting Standards Codification (“ASC”) Topic 815. The guidance revised previously existing guidance for determining whether
an Instrument (or embedded feature) is indexed to an entity’s own stock. Equity-linked instruments (or embedded features) that otherwise meet
the definition of a derivative are not accounted for as derivatives if certain criteria are met, one of which is that the instrument (or embedded
feature) must be indexed to the entity’s own stock. The Company applied the new guidance to outstanding instruments as of October 1, 2009.
The fair value of the warrants affected by the new guidance at the dates of issuance totaled $8,282,000 and was initially recorded as a
component of additional paid-in capital. Upon adoption of the new guidance, the Company recorded a decrease to the opening balance of
additional-paid-in capital of $8,142,000 and recorded a decrease to accumulated deficit totaling $4,353,000, representing the decrease in the
fair value of the warrants from the date of issuance to October 1, 2009. The fair value of the warrants at October 1, 2009 of $3,789,000 was
classified as a liability in the balance sheet.

       Increases or decreases in fair value of the warrants are included as a component of other income (expense) in the accompanying
statement of operations for the respective period. As of September 30, 2011, the liability for warrants decreased to approximately $23,405,000
from approximately $27,549,000 as of September 30, 2010, as a result of a net decrease of warrant activity of $257,000 and a gain to the
statements of operations for the fiscal year ended September 30, 2011 of approximately $3,887,000. The warrant liability and revaluations have
not and will not have any impact on the Company’s working capital, liquidity or business operations. Some of the Company's warrants contain
terms that limit the number of shares the Company would be required to issue thereunder unless the warrant holder agrees to increase the limit
prior to exercise. If the warrants outstanding as of September 30, 2011 were exercised in full without regard to any current exercise limits
contained therein, the Company would be required to issue a maximum of 61,039,999 shares of common stock.

C. Liquidity

      The accompanying financial statements have been prepared assuming the Company will continue as a going concern, which
contemplates the realization of assets and the liquidation of liabilities in the normal course of business.

        The Company has incurred significant cash outflows from operations of approximately $3,102,000, $2,446,000 and $1,923,000 for the
fiscal years ended September 30, 2011, 2010 and 2009, respectively. The Company had net income of approximately $299,000 (including a
non-cash gain adjustment for decreases in valuation of warrants of approximately $3,887,000) for the year ended September 30, 2011. The
Company had net losses from operations of approximately $25,869,000 (including a non-cash charge for increases in valuation of warrants of
$21,347,000) and $2,296,000 for the years end September 30, 2010 and 2009, respectively. The Company expects to incur additional losses
and cash outflows from operations for several more years.
F-23
        As a result of the financings which are discussed more fully in Note G–Stockholders’ Equity, the Company was able to: (i) raise
approximately $1,650,000 during the first quarter of fiscal year 2010; (ii) raise additional gross proceeds of $1,650,000 in the fourth quarter of
fiscal year 2010; (iii) complete a common stock and warrant financing for gross proceeds of $1,000,000 in the fourth quarter of fiscal year
2010, with the option by the Company to put or holder to call another $1,000,000 during the first quarter of fiscal 2011. During the first quarter
of fiscal year 2011, the holder called its option, resulting in gross proceeds of $1,000,000 to the Company.

        If the Company is unable to obtain additional funding for its operations, it will need to eliminate or substantially limit some or all of its
activities, merge with another company, sell, lease or license some or all of its assets, or cease operations entirely. There can be no assurance
that the Company will be able to obtain additional financing on favorable terms, or at all, or that the Company will be able to merge with
another Company or sell, lease or license any or all of its assets. This raises substantial doubt about the Company’s ability to continue as a
going concern. These financial statements do not include any adjustments that might result from this uncertainty.

D. Investments

Investment in CPEC LLC

       The Company uses the equity method to account for its 35.0% ownership interest in CPEC. During fiscal 2003, CPEC licensed
bucindolol, a drug previously under development by the Company for the treatment of heart failure, to ARCA in return for possible future
royalty and milestone payments. During fiscal 2008, CPEC declared and paid a dividend of which the Company received $175,000. The
dividend was paid upon receipt of a milestone payment by CPEC from ARCA, which was triggered upon the filing of a New Drug Application
for bucindolol with the FDA. Also as a result of the filing of the New Drug Application with the FDA, the Company was obligated to pay
$413,000, which the Company elected to pay in the form of stock to the majority owner of CPEC who in turn paid the original licensors of
bucindolol per the terms of the 1994 Purchase Agreement of CPEC. On November 6, 2009, we issued 1,099,649 shares to the majority owner
of CPEC to satisfy the obligation.

       CPEC had $91,000 of net assets at each of September 30, 2011 and 2010. Aeolus’ share of CPEC’s net assets is included in other assets
and the Company has no operations or activities unrelated to the out licensing of bucindolol.

E. Commitments

       The Company acquires assets still in development and enters into license and research and development arrangements with third parties
that often require milestone and royalty payments to the third party contingent upon the occurrence of certain future events linked to the
success of the asset in development. Milestone payments may be required, contingent upon the successful achievement of an important point in
the development life-cycle of the pharmaceutical product (e.g., approval of the product for marketing by a regulatory agency). If required by
the arrangement, the Company may also be required to make royalty payments based upon a percentage of the net sales of the pharmaceutical
product in the event that regulatory approval for marketing is obtained. Because of the contingent nature of these payments, they are not
included in the table of contractual obligations. No milestones have been met, nor have any payments been paid, as of September 30, 2011.

       We are also obligated to pay patent filing, prosecution, maintenance and defense costs, if any, for the intellectual property the Company
has licensed from National Jewish Health ("NJH"), National Jewish Medical and Research Center (the “NJMRC”) and Duke University.

F. Notes Payable

Senior Convertible Notes to Related Parties

        On August 1, 2008, the Company entered into a Securities Purchase Agreement (the “SCN Purchase Agreement”) with three accredited
institutional investors (the “August 2008 Investors”) pursuant to which the Company agreed to sell, to the August 2008 Investors, units
comprised of senior unsecured convertible notes of the Company (the “Notes”), in an aggregate principal amount of up to $5,000,000, which
bear interest at a rate of 7% per year and mature on the 30-month anniversary of their date of issuance, and warrants to purchase up to an
aggregate of 10,000,000 additional shares of the Company’s common stock (the “August 2008 Warrant Shares”), each with an initial exercise
price of $0.50 per share, subject to adjustment as provided in the warrant agreements (the “August 2008 Warrants”). Each unit (collectively, the
“August 2008 Units”) is comprised of $1,000 in Note principal and August 2008 Warrants to purchase up to 2,000 shares of the Company’s
common stock, and has a purchase price of $1,000.


                                                                         F-24
      On August 1, 2008, pursuant to the SCN Purchase Agreement, the Company sold and issued to the August 2008 Investors, an aggregate
of 500 August 2008 Units comprised of Notes in the aggregate principal amount of $500,000 and August 2008 Warrants to purchase up to
1,000,000 shares of common stock for an aggregate purchase price of $500,000 (the “SCN Financing”).

      On each of September 4, 2008, October 1, 2008, November 3, 2008 and December 1, 2008, the Company sold and issued to the
August 2008 Investors an aggregate of 125 August 2008 Units comprised of Notes in the aggregate principal amount of $125,000 and
August 2008 Warrants to purchase up to 250,000 shares of common stock for an aggregate purchase price of $125,000 (the “Subsequent
Financings”).

       The Notes issued in the SCN Financing and the Subsequent Financings had an initial conversion price of $0.35 per share, subject to
adjustment as provided in the Notes. In addition, the August 2008 Investors had the option to purchase up to an additional 4,000 August 2008
Units, in one or more closings at their sole option at any time on or before December 31, 2013.

       Interest on the Notes accrued at the rate of 7.0% per annum from the date of issuance, and was payable semi-annually, on January 31 and
July 31 of each year. Interest was payable, at the Company’s sole election, in cash or shares of common stock, to holders of Notes on the record
date for such interest payments, with the record dates being each January 15 and July 15 immediately preceding an interest payment date. The
effective interest rate of the Notes, including the effect of the amortization of the embedded conversion feature and the note discount, was
39.4%.

       The net proceeds to the Company from the sale of 1,000 August 2008 Units in the SCN Financing and Subsequent Financing, after
deducting for expenses, were approximately $844,000. The Company used the net proceeds to fund the development of AEOL 10150 and to
fund ongoing operations of the Company. Offering costs of the private placement were $156,000 and were allocated to the Notes and
August 2008 Warrants based upon their respective fair values. The offering costs attributed to the Notes in the amount of $100,000 were
capitalized as Debt Issuance Costs. The Debt Issuance Costs were amortized over the life of the Notes in the SCN Financing.

       Pursuant to the Securities Purchase and Exchange Agreement dated October 6, 2009 (the “October 2009 Purchase Agreement”), as more
fully described in Note G – Stockholders’ Equity, the holders of the Notes agreed to convert all $1,000,000 in principal amount of the Notes
into common stock at a conversion rate of $0.35 per share and to exchange their remaining option to purchase an additional $4,000,000 in
Notes for warrants to purchase up to 14,285,714 shares of common stock with an initial exercise price of $0.28 per share, subject to adjustment
as provided in the warrants.

       On December 24, 2009, the Company entered into an amendment (the “Amendment”) to the October 2009 Purchase Agreement,
pursuant to which the Company agreed to lower the conversion price of the Notes from $0.35 per share to $0.28 per share and as a result,
issued an additional 714,286 shares of common stock to the former holders of the Notes. The Amendment was executed to resolve a
misunderstanding regarding one of the financing terms in the October 6, 2009 financing between the Company and the investors in the
financing. The Company did not receive any proceeds from the issuance. As a result of the Amendment and the issuance of the additional
shares, the Company recorded a charge of $343,000 in the Statement of Operations as interest expense for the value of the shares issued on the
date of issuance.

       Affiliates of Xmark Opportunity Partners, LLC were the sole investors in the SCN Financing. Together with its affiliates, Xmark

                                                                     F-25
Elan Note Payable

        In August 2002, Aeolus borrowed $638,000 from Elan Corporation, plc (“Elan”) pursuant to a promissory note. The note payable
accrued interest at 10% compounded semi-annually. The note was convertible at the option of Elan into shares of the Company’s Series B
non-voting convertible preferred stock (“Series B Stock”) at a rate of $43.27 per share. The original note matured on December 21, 2006.
However, in February 2007, the Company and Elan terminated the note, the Company paid $300,000 in cash to Elan, Elan forgave $225,000 of
the note payable and Elan and the Company entered into a new two-year note payable in the amount of $453,000 under substantially the same
terms as the original note. In February 2009, the Company and Elan agreed to amend the new note payable to extend its maturity date from
February 7, 2009 to February 7, 2011 and increased the interest rate of the convertible promissory note from 10% to 11% effective February 7,
2009. As of the date of the amendment, an aggregate of $553,000 in principal and interest was outstanding under the convertible promissory
note. In the event of an event of default under the convertible promissory note, Elan may demand immediate payment of all amounts
outstanding under the note. For purposes of the note, an event of default includes, among other items, a default in the payment of the note
principal or interest when due and payable, an uncured breach by the Company of its obligations to Elan pursuant the agreements under which
the convertible promissory note was issued, an inability of the Company to pay its debts in the normal course of business, the cessation of
business activities by the Company (other than as a result of a merger or consolidation with a third party) without Elan’s prior written consent
and the appointment of a liquidator, receiver, administrator, examiner, trustee or similar officer of the Company or over all or substantially all
of its assets under the law.

       During the term of the note payable, Elan has the option to convert the note into shares of Series B Stock at a rate of $9.00 per share.
Upon the maturity of the note payable, Aeolus has the option to repay the note either in cash or in shares of Series B Stock and warrants having
a then fair market value equal to the amount due under the note; provided that the fair market value used for calculating the number of shares to
be issued will not be less than $13.00 per share. As of September 30, 2010 and 2009, the outstanding balance, including interest, on the note
payable to Elan was approximately $663,000 and 594,000, respectively.

       On February 7, 2011, the due date of the loan, Aeolus elected to exercise its right to repay the note, with a maturity value of
approximately $663,000, with 50,993 shares of Series B Stock and a warrant to purchase an aggregate of 896,037 shares of Series B Stock at an
exercise price of $0.01 per share. The warrant has a term of five years, a cashless exercise provision and customary anti-dilution adjustments in
the event of stock splits, stock combination, reorganizations and similar events. In connection with the issuance, Aeolus amended its certificate
of incorporation on February 7, 2011 to increase the authorized number of shares of Series B Stock from 600,000 to 1,600,000. The fair value
of the warrants issued on February 7, 2011 was estimated to be $452,000 using the Black-Scholes option pricing model with the following
assumptions: dividend yield of 0%, expected volatility of 93.3%, risk free interest rate of 2.39% and an expected life of five years.

Basis of Presentation

Preferred Stock

       The Certificate of Incorporation of Aeolus authorizes the issuance of up to 10,000,000 shares of Preferred Stock, at a par value of $0.01
per share, of which 1,250,000 shares are designated Series A Convertible Preferred Stock and 1,600,000 shares are designated Series B
Convertible Preferred Stock. The Board of Directors has the authority to issue Preferred Stock in one or more series, to fix the designation and
number of shares of each such series, and to determine or change the designation, relative rights, preferences, and limitations of any series of
Preferred Stock, without any further vote or action by the stockholders of the Company.

       In January 2001, Aeolus issued to Elan 28,457 shares of Series B Stock. In February 2002, the Company issued 58,883 additional shares
of Series B Stock and 480,000 shares of common stock to Elan in exchange for the retirement of a $1,400,000 note payable to Elan. In
May 2002, the Company sold 416,204 shares of Series B Stock to Elan for $3,000,000. On January 14, 2005, Elan converted 28,457 shares of
the Series B Stock into 28,457 shares of common stock. As of September 30, 2011 and 2010, 526,080 and 475,087 shares of Series B Stock
were outstanding, respectively. There are no shares of Series A Convertible Preferred Stock issued or outstanding.

       With respect to dividend rights and rights upon liquidation, winding up and dissolution, the Series B Stock ranks pari passu with the
common stock. Subject to any rights of senior stock, holders of Series B Stock are entitled to receive dividends or distributions as, when and if
declared by the Board of Directors. In the event the Board of Directors declares a dividend or distribution with respect to the outstanding
common stock, the holders of Series B Stock are entitled to receive the amount of dividends per share in the same form payable on the common
stock based on the largest number of shares of common stock issuable upon conversion of the outstanding Series B Stock. In the event of a
liquidation, winding up or dissolution of the Company, subject to any rights of senior stock, the holders of Series B Stock are entitled to
receive, pari passu with the holders of the common stock, the assets of the Company based on the largest number of shares of common
stock issuable upon conversion of the outstanding Series B Stock.


                                                                      F-26
       Each share of Series B Stock is convertible into one share of common stock. The Series B Stock can be converted into common stock at
any time upon the election of the holders of the Series B Stock except to the extent such conversion would result in the holders of Series B
Stock owning in the aggregate more than 9.99% of the outstanding common stock.

       The Series B Stock is not entitled to vote on any matter submitted to the vote of holders of the common stock except that the Company
must obtain the approval of a majority of the outstanding shares of Series B Stock to either amend the Company’s Certificate of Incorporation
in a manner that would adversely affect the Series B Stock (including by creating an additional class or series of stock with rights that are
senior or pari passu to the Series B Stock) or change the rights of the holders of the Series B Stock in any other respect.

Common Stock

August-December 2008 Financing

      In connection with the Senior Convertible Note Financing, Aeolus issued warrants to purchase 2,000,000 shares at an exercise price of
$0.50 per share with a five year term. The fair value of the warrants issued on August 1, 2008 was estimated to be $282,000 using the
Black-Scholes option pricing model with the following assumptions: dividend yield of 0%; expected volatility of 128%; risk free interest rate
of 3.2%; and an expected life of five years. The fair value of the warrants issued on September 4, 2008 was estimated to be $53,000 using the
Black-Scholes option pricing model with the following assumptions: dividend yield of 0%; expected volatility of 130%, risk free interest rate
of 3.0%; and an expected life of five years. The fair value of the warrants issued on October 1, 2008 was estimated to be $93,000 using the
Black-Scholes option pricing model with the following assumptions: dividend yield of 0%; expected volatility of 133%, risk free interest rate
of 2.9%; and an expected life of five years. The fair value of the warrants issued on November 3, 2008 was estimated to be $76,000 using the
Black-Scholes option pricing model with the following assumptions: dividend yield of 0%; expected volatility of 139%, risk free interest rate
of 2.7%; and an expected life of five years. The fair value of the warrants issued on December 1, 2008 was estimated to be $75,000 using the
Black-Scholes option pricing model with the following assumptions: dividend yield of 0%; expected volatility of 138%, risk free interest rate
of 1.7%; and an expected life of five years.

March 2009 Financing

       On March 30, 2009, Aeolus entered into a Securities Purchase Agreement (the “Purchase Agreement”) with two accredited institutional
investors (the “March 2009 Investors”) pursuant to which the Company sold and issued to the March 2009 Investors in a private placement an
aggregate of 5,357,143 units (the “March 2009 Units”), comprised of an aggregate of 5,357,143 shares of common stock of the Company and
warrants to purchase up to an aggregate of 13,392,857 additional shares of common stock (the “March 2009 Warrants”), with an initial exercise
price of $0.35 per share, subject to adjustment as provided in the March 2009 Warrants, with each March 2009 Unit representing one share of
common stock and a March 2009 Warrant to purchase two-and-one-half shares of common stock, at a purchase price of $0.28 per March 2009
Unit for aggregate gross proceeds of $1,500,000 (collectively, the “March 2009 Financing”). The March 2009 Warrants are exercisable for a
five year period from their date of issuance; contain a “cashless exercise” feature that allows the holder to exercise the March 2009 Warrants
without a cash payment to the Company under certain circumstances; contain a dividend participation right which allows the holder to receive
any cash dividends paid on the Company’s common stock without exercising the March 2009 Warrant and contain a provision that provides for
the reduction of the exercise price to $0.01 in the event of any such payment of cash dividends by the Company; and contain standard
anti-dilution provisions that provide for the adjustment of the exercise price and the number of shares of common stock that can be purchased
in the event of a financing at a price per share below the exercise price, a stock dividend or split, dividend payment or other issuance,
reorganization, recapitalization or similar event.

      The fair value of the March 2009 Warrants was estimated to be $4,129,000 using the Black-Scholes option pricing model with the
following assumptions: dividend yield of 0%; risk free interest rate of 1.7%; expected volatility of 164%; and an expected life of five years.

      Offering costs of the March 2009 Financing were $91,000 resulting in net proceeds to the Company of approximately $1,400,000. The
Company has used, and intends to continue to use, the net proceeds from the March 2009 Financing to finance the development of AEOL
10150 and to fund ongoing operations of the Company. Affiliates of Xmark Opportunity Partners, LLC were the sole investors in the
March 2009 Financing.


                                                                      F-27
        As a result of the March 2009 Financing, the Company was required to lower the exercise price of 4,687,000 warrants previously issued
in November 2005 and May 2007 to $0.28 per share, the purchase price of the March 2009 Units. As a result of the change in the exercise
price, these warrants were revalued resulting in an increase in the value of $38,000, which was charged to the statement of operations during
the second quarter of fiscal year 2009.

October 2009 Financing

       On October 6, 2009, the Company entered into the October 2009 Purchase Agreement with several accredited institutional investors (the
“October 2009 Investors”) pursuant to which the Company sold and issued to the October 2009 Investors in a private placement an aggregate
of 5,892,857 units (the “October 2009 Units”), comprised of an aggregate of 5,892,857 shares of common stock (the “October 2009 Shares”)
and warrants to purchase up to an aggregate of 11,785,714 additional shares of common stock (the “October 2009 Warrants”), with an initial
exercise price of $0.28 per share, subject to adjustment as provided in the October 2009 Warrants, with each October 2009 Unit representing
one share of common stock and a October 2009 Warrant to purchase two shares of common stock, at a purchase price of $0.28 per
October 2009 Unit for aggregate gross proceeds of $1,650,000 (collectively, the “October 2009 Financing”). The October 2009 Warrants are
exercisable for a seven year period from their date of issuance; contain a “cashless exercise” feature that allows the holder to exercise the
October 2009 Warrants without a cash payment to the Company under certain circumstances; contain a dividend participation right which
allows the holder to receive any cash dividends paid on the common stock without exercising the October 2009 Warrant and contain a
provision that provides for the reduction of the exercise price to $0.01 in the event of any such payment of cash dividends by the Company or
upon a change of control and contain anti-dilution provisions in the event of a stock dividend or split, dividend payment or other issuance,
reorganization, recapitalization or similar event.

       The Company also granted to the October 2009 Investors the option to acquire, collectively, up to an additional 5,892,857 October 2009
Units (the “Additional Units”), comprised of an aggregate of 5,892,857 shares of common stock and warrants to purchase up to an aggregate of
11,785,714 additional shares of common stock at the per Additional Unit purchase price of $0.28 (the “October 2009 Call Option”). In
addition, the October 2009 Investors granted to the Company the option to require these October 2009 Investors, severally and not jointly, to
acquire up to 5,892,857 Additional Units, less any Additional Units acquired under the October 2009 Call Option, at the per Additional Unit
purchase price of $0.28 (the “October 2009 Put Option”). The October 2009 Call Option was exercisable at any time, and from time to time, on
or prior to June 30, 2010. The October 2009 Put Option was exercisable at any time from June 30, 2010 to July 30, 2010. On July 30, 2010, the
Company exercised the October 2009 Put Option in full for $1,650,000 in gross cash proceeds and issued 5,892,857 shares of common stock
and 11,785,714 warrants to the October 2009 Investors.

       In addition, the October 2009 Investors agreed to convert all $1,000,000 in principal amount of the Notes into common stock of the
Company at a conversion rate of $0.35 per share (the “Conversion Shares”), which was subsequently lowered to $0.28 as discussed below, and
to exchange their remaining option to purchase an additional $4,000,000 in Notes for warrants to purchase up to 14,285,714 shares of common
stock in substantially the same of form and terms of the October 2009 Warrants issued in the October 2009 Financing, including an initial
exercise price of $0.28 per share, subject to adjustment as provided in the warrants (the “Note Warrants”). As consideration for the
October 2009 Investors to convert the Notes, the Company agreed to exchange warrants to purchase up to 2,000,000 shares of common stock
issued to the October 2009 Investors in connection with the sale of the Notes, warrants to purchase up to 2,150,000 shares of common stock
issued to the October 2009 Investors and one of their affiliates in connection with a financing completed in November 2005 and warrants to
purchase up to 13,392,857 shares of common stock issued to the October 2009 Investors in connection with a financing completed in
March 2009 (collectively, the “Prior Warrants”) for warrants to purchase up to an aggregate of 17,542,857 shares of common stock in
substantially the same form and terms of the October 2009 Warrants issued in the October 2009 Financing, including an initial exercise price of
$0.28 per share, subject to adjustment pursuant to the warrants (the “Exchange Warrants”) (collectively, the “Conversion”).

       In connection with the October 2009 Financing and the Conversion, the Company also entered into a Registration Rights Agreement (the
“October 2009 Rights Agreement”) with the October 2009 Investors. In addition, the October 2009 Investors agreed to terminate the
Company’s Registration Rights Agreements dated November 21, 2005 and March 30, 2009. Pursuant to the October 2009 Rights Agreement,
the Company agreed to file one or more registration statements (collectively, the “Registration Statements”) with the Securities and Exchange
Commission (the “SEC”) covering the resale of the October 2009 Shares, the Conversion Shares and all shares of common stock issuable upon
exercise of the October 2009 Warrants, the Note Warrants and the Exchange Warrants (collectively, the “Registrable Securities”) upon demand
of the holders of a majority of the Registrable Securities (a “Demand Registration”). Such holders have the right to two Demand Registrations,
subject to certain exceptions. In the event the holders exercise their right to a Demand Registration, the Company has agreed to file a
Registration Statement to register the resale of the Registrable Securities within a certain number of days after the request and to use
commercially reasonable efforts to cause the Registration Statement to be declared effective by the SEC as soon as practicable after the filing
thereof. The Company also agreed to use its commercially reasonable efforts to keep the Registration Statements effective for a specified
period.


                                                                     F-28
      The net proceeds to the Company from the October 2009 Financing, after deducting for expenses, were approximately $1,600,000. The
Company has used, and intends to continue to use, the net proceeds from the October 2009 Financing to finance animal efficacy studies in
Acute Radiation Syndrome, the development of AEOL 10150 and ongoing operations of the Company.

       The fair value of the October 2009 Warrants, the Note Warrants and the Exchange Warrants was estimated to be $10,585,000 using the
Black-Scholes option pricing model with the following assumptions: dividend yield of 0%; expected volatility of 93%; risk free interest rate of
2.9%; and an expected life of seven years. The fair value of the Prior Warrants cancelled on October 6, 2009 was $3,352,000. The proceeds
from the October 2009 Financing were allocated based upon the relative fair values of the October 2009 Warrants and the October 2009
Shares. Due to the anti-dilution provisions of the October 2009 Warrants, the Note Warrants and the Exchange Warrants, these warrants were
deemed to be a liability under current accounting guidance and as a result the warrant liability was increased by $7,233,000, of which
$6,213,000 was recorded as a charge to the Statement of Operations, and $1,020,000 of proceeds from the October 2009 Financing was
allocated to the value of the October 2009 Warrants.

        Affiliates of Xmark Opportunity Partners, LLC were the sole investors in the October 2009 Financing and, together with the Company,
were the sole participants in the Conversion. Together with its affiliates, Xmark Opportunity Partners, LLC beneficially owned approximately
71% of the Company’s outstanding common stock prior to the October 2009 Financing and the Conversion. Xmark Opportunity Partners, LLC
is the sole manager of Goodnow and possesses sole power to vote and direct the disposition of all securities of the Company held by Goodnow.
Goodnow has the right to designate up to two directors for election to the Company’s Board of Directors pursuant to the terms of a purchase
agreement between Goodnow and the Company. David C. Cavalier, a current employee, director and Chairman of the Board of the Company,
and Managing Partner of Xmark Opportunity Partners LLC, is President of Goodnow.

       On December 24, 2009, the Company entered into an amendment (the “Amendment”) to the October 2009 Purchase Agreement
pursuant to which the Company agreed to lower the conversion price of the Notes from $0.35 per share to $0.28 per share and as a result,
issued to the investors in the Company’s October 2009 Financing an additional 714,286 shares of the Company’s common stock upon
conversion of the Notes (the “Issuance”). The Agreement was executed to resolve a misunderstanding regarding one of the financing terms
between the Company and the October 2009 Investors. The Company did not receive any proceeds from the Issuance. The fair value of the
common stock on the date of issuance was $343,000 and was charged to the Statement of Operations as interest expense.

       On July 30, 2010, the Company exercised the October 2009 Put Option. As a result of the exercise, the Company received $1.65 million
in gross proceeds from the investors in exchange for 5,892,857 additional Units (the “Additional Units”), comprised of an aggregate of
5,892,857 shares of common stock and warrants to purchase up to an aggregate of 11,785,714 additional shares of common stock at a purchase
price of $0.28 per share.

       Net cash proceeds from the exercise of the October 2009 Put Option were approximately $1.6 million after legal costs associated with
the exercise and subsequent issuance of stock and warrants.

        The fair value of the October 2009 Put Option Warrants exercised on July 30, 2010 was estimated to be $3,911,000 using the
Black-Scholes option pricing model with the following assumptions: dividend yield of 0%, expected volatility of 92.0%, risk free interest rate
of 2.30% and an expected life of seven years. The proceeds from the October 2009 Put Option exercise were allocated based upon the relative
fair values of the October 2009 Put Option Warrants and the October 2009 Put Option Shares. Due to the anti-dilution provisions of the
October 2009 Put Option Warrants, these warrants were deemed to be a liability under current accounting guidance and as a result the warrant
liability was increased by $3,911,000 of which $2,882,000 was recorded as a charge to the Statement of Operations and $1,029,000 of proceeds
from the October 2009 Put Option exercise was allocated to the value of the October 2009 Put Option Warrants.

August 2010 Financing

       On August 12, 2010, the Company announced an additional financing with certain existing investors (the “August 2010 Investors”).
Under the terms of the agreement, the Company received $1,000,000 in gross proceeds in exchange for the issuance of 2,500,000 shares of
common stock and warrants to purchase up to 1,875,000 shares at an exercise price of $0.50 per share. The Company also granted to the
August 2010 Investors the option to acquire, collectively, up to an additional 2,500,000 units, comprised of an aggregate of 2,500,000 shares of
common stock and warrants to purchase up to an aggregate of 1,875,000 additional shares of common stock at an exercise price of $0.50 (the
“August 2010 Call Option”). In addition, the August 2010 Investors granted to the Company the option to require these August 2010 Investors,
severally and not jointly, to acquire up to 2,500,000 additional units, less any additional units acquired under the August 2010 Call Option, at
the per additional unit purchase price of $0.40 (the “August 2010 Put Option”). On December 28, 2010, the investors exercised their Call
Option and the Company received $1 million in proceeds in exchange for 2,500,000 common shares and 1,875,000 warrants.


                                                                     F-29
      Net cash proceeds from the August 2010 Financing, after deducting for expenses, were approximately $900,000.

       The fair value of the August 2010 Warrants was estimated to be $542,000 using the Black-Scholes option pricing model with the
following assumptions: dividend yield of 0%; expected volatility of 91.83%; risk free interest rate of 2.08%; and an expected life of seven
years. The proceeds from the August 2010 financing were allocated based upon the relative fair values of the August 2010 Warrants and the
August 2010 Shares. Due to the anti-dilution provisions of the August 2010 Warrants, these warrants were deemed to be a liability under
current accounting guidance and, as a result, the warrant liability was increased by $542,000 of which $179,000 was recorded as a charge to the
Statement of Operations and $363,000 of proceeds from the August 2010 financing was allocated to the value of the August 2010 Warrants.

        On December 28, 2010, the investors exercised their Call Option and the Company received $1,000,000 in proceeds in exchange for
2,500,000 common shares and 1,875,000 warrants, with an initial exercise price of $0.50 per share, subject to adjustment as provided in the
warrants (the “Additional Warrants”). The Additional Warrants are exercisable for a seven-year period from their date of issuance; contain a
“cashless exercise” feature that allows the holder to exercise the Additional Warrants without a cash payment to the Company under certain
circumstances; contain a dividend participation right which allows the holder to receive any cash dividends paid on the common stock without
exercising the Additional Warrant; contain a provision that provides for the reduction of the exercise price to $0.01 in the event of any such
payment of cash dividends by the Company or upon a change of control; and contain anti-dilution provisions in the event of a stock dividend or
split, dividend payment or other issuance, reorganization, recapitalization or similar event.

      The net cash proceeds to the Company from the December 2010 financing, after deducting for expenses, were approximately $990,000.

       The fair value of the August 2010 Call Option warrants was estimated to be $912,000 using the Black-Scholes option pricing model with
the following assumptions: dividend yield of 0%; expected volatility of 90.51%; risk free interest rate of 2.89%; and an expected life of seven
years. The proceeds from the August 2010 Call Option exercise were allocated based upon the relative fair values of the August 2010 Call
Option Warrants and the August 2010 Put Option Shares. Due to the anti-dilution provisions of the August 2010 Call Option Warrants, these
warrants were deemed to be a liability under current accounting guidance and as a result the warrant liability was increased by $912,000 of
which $534,000 was recorded as a charge to the Statement of Operations and $378,000 of proceeds from the August 2010 Call Option exercise
was allocated to the value of the October 2009 Warrants.

Dividends

        The Company has never paid a cash dividend on its common stock and does not anticipate paying cash dividends on its common stock
in the foreseeable future. If we pay a cash dividend on our common stock, we also must pay the same dividend on an as converted basis on our
Series B preferred stock. In addition, under the terms of the warrants to purchase up to 61,822,749 shares of our common stock issued to
Xmark Opportunity Partners, LLC or its affiliates (“Xmark”) in three transactions (on each of October 6, 2009, July 30, 2010 and August 11,
2010), and any additional warrants issued pursuant to the put and/or option right granted in our August 2010 financing, if we were to pay a
dividend on our common stock, the exercise price of these warrants would be reset from $0.28 per share or $0.50 per share, as applicable, to
$0.01 per share and the warrant holders would also be entitled receive any such dividend paid.

Warrants

H. Stock-Based Compensation

        As an integral component of a management and employee retention program designed to motivate, retain and provide incentive to the
Company’s management, employees and key consultants, the Board of Directors approved the 2004 Stock Option Plan (the “2004 Plan”) and
reserved 10,000,000 shares of common stock for issuance under the 2004 Plan. As of September 30, 2011, 2,867,159 shares were available to
be granted under the 2004 Plan. The exercise price of the incentive stock options (“ISOs”) granted under the 2004 Plan must not be less than
the fair market value of the common stock as determined on the date of the grant. The options may have a term up to 10 years. Options
typically vest immediately or up to one year following the date of the grant. Under the Company’s 1994 Stock Option Plan (the “1994 Plan”),
incentive stock options or non-qualified stock options to purchase 2,500,000 shares of Aeolus’ common stock may be granted to employees,
directors and consultants of the Company. As of September 30, 2011, there were no shares available to be granted under the 1994 Plan. The

      The fair value of the options associated with the above compensation expense was determined at the date of the grant using the
Black-Scholes option pricing model with the following weighted average assumptions:

                                                                            For the fiscal year ended September 30,

       Effective July 1, 2011, the Company began using historical information regarding the volatility of its own stock price for purposes
of calculating an expected volatility rate for stock option valuation purposes. From April 1, 2009 through June 30, 2011, the Company used a
peer group of publicly traded entities to determine an expected volatility rate for stock option valuation. There was no material impact on the
financial statements as a result of this change as of July 1, 2011. In addition, the Company changed its method of amortization of stock-based
compensation from the multiple attribute method to straight line for option grants made on and subsequent to April 1, 2009. There was no
material impact on the financial statements as a result of this change as of April 1, 2009. The Company believes the use of its historical stock
price and straight line amortization results in a better estimate of the Company’s stock-based compensation expense.


                                                                         F-34
I. Income Taxes

       As of September 30, 2011 and 2010, the Company had federal net operating loss (“NOL”) carry-forwards of $111,347,000 and
$109,695,000, respectively and state operating loss carry-forwards of $34,757,000 and $33,106,000, respectively. The use of these federal and
state NOL carry-forwards might be subject to limitation under the rules regarding a change in stock ownership as determined by the Internal
Revenue Code (the “Code”). The Company may have had a change of control under Section 382 of the Code during fiscal 2004 and 2006;
however, a complete analysis of the limitation of the NOL carry-forwards will not be completed until the time the Company projects it will be
able to utilize such NOLs. The federal net operating and the state net operating losses began to expire in 2010. Additionally, the Company had
federal research and development carry-forwards as of September 30, 2011 and 2010 of $3,329,000 and $3,132,000, respectively. The
Company had state research and development carry-forwards as of September 30, 2011 and 2010 of $624,000 and $424,000, respectively.

      Significant components of the Company’s deferred tax assets at September 30, 2011 and 2010 consisted of the following (in thousands):

                                                                                      2011               2010
                             Net operating loss carry-forwards                 $         40,939     $       40,223

                             Total deferred tax assets                                   46,192              46,405
                             Deferred tax liabilities                                        —                   —
                             Valuation allowance for deferred assets                    (46,192 )           (46,405 )
                             Net deferred tax asset                            $             —      $            —


      Due to the uncertainty surrounding the realization of the favorable tax attributes in future tax returns, all of the deferred tax assets have
been fully offset by a valuation allowance. The change in the valuation allowance is primarily a result of the net operating loss carry-forwards.

      Taxes computed at the statutory federal income tax rate of 34% are reconciled to the provision for income taxes as follows (dollars in
thousands):
